The six star forming reg ions in the complex are in the evolutionary stages: early protostellar pha se (W33 Main1)\, protostellar phase (W33 A1\, W33B1)\, hot core phase (W33 A\, W33B)\, and HII region phase (W33Main). Since N2H+ and CS trace the c old and dense gas and their abundances are normally quite high\, these mol ecules are easily detected in star forming regions. From previous APEX obs ervations\, we determined the integrated intensity ratio N2H+(3-2)/CS(6-5) in the six W33 sources. This ratio follows a clear trend as a function of the evolutionary stage of the targets and is a good candidate for a "chem ical clock". In combination with APEX observations of N2H+(2-1) and CS(4-3 ) and previously obtained H2 column densities\, we determined the abundanc es of these two molecules\, using radiative transfer models. I will presen t the results and show how we tested the abundance ratio of N2H+/CS as a c hemical clock in W33.\n\nhttps://events.mpifr-bonn.mpg.de/indico/event/58/ session/8/contribution/28 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/28 END:VEVENT BEGIN:VEVENT SUMMARY:Star-formation and the Galactic environment: a field trip to the o uter Galaxy DTSTART;VALUE=DATE-TIME:20180312T164000Z DTEND;VALUE=DATE-TIME:20180312T170000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-22@cern.ch DESCRIPTION:Speakers: KÖNIG\, Carsten ()\nExtending our knowledge on star -formation to the outer Galaxy and comparing it to the properties found in the inner parts of the Milky Way helps us understand the influence of the Galactic environment on star-formation. For this purpose we used the APEX telescope to conduct pointed CO(2-1) observations towards more than 800 c lumps identified from Hi-GAL 250 micron dust continuum emission maps. Bein g able to identify more than 1700 velocity components and calculating thei r kinematic distances\, we were able to unravel the structure of the south ern outer Galaxy in unprecedented detail with a project that was mainly ob served just as a bad weather backup project at APEX. With the distances kn own\, we were furthermore able to calculate physical parameters of the clu mps from dust spectral energy distributions such as dust temperature\, bol ometric luminosities\, clump masses and column densities. In this talk we will not only present the structure and physical parameters found in the s outhern outer Galaxy\, but also investigate their dependence on Galactocen tric radius (by comparing them to the results found for the inner Galaxy b y ATLASGAL and Hi-GAL)\, the influence of an expanding Galactic supershell present in the observed region as well as the correlation of star-formati on properties with the supposed loci of the spiral arms. Finally we will i ntroduce you to our planned CO mapping campaign for the southern outer Gal axy at APEX that will allow a complete and much more detailed view on on t his exciting part of the Milky Way.\n\nhttps://events.mpifr-bonn.mpg.de/in dico/event/58/session/8/contribution/22 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/22 END:VEVENT BEGIN:VEVENT SUMMARY:Modelling the emission of nitrogen-bearing molecules towards the s olar type protostar IRAS 16293-2422 DTSTART;VALUE=DATE-TIME:20180313T105000Z DTEND;VALUE=DATE-TIME:20180313T111000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-29@cern.ch DESCRIPTION:Speakers: HERNANDEZ-GOMEZ\, Antonio ()\nhttps://events.mpifr-b onn.mpg.de/indico/event/58/session/8/contribution/29 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/29 END:VEVENT BEGIN:VEVENT SUMMARY:C\, CO\, H2 and X in high and low metallicity galaxies DTSTART;VALUE=DATE-TIME:20180314T080000Z DTEND;VALUE=DATE-TIME:20180314T082000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-53@cern.ch DESCRIPTION:Speakers: ISRAEL\, Frank ()\nhttps://events.mpifr-bonn.mpg.de/ indico/event/58/session/11/contribution/53 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contributi on/53 END:VEVENT BEGIN:VEVENT SUMMARY:The Atacama Large-Aperture Submm/mm Telescope DTSTART;VALUE=DATE-TIME:20180314T105000Z DTEND;VALUE=DATE-TIME:20180314T111000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-52@cern.ch DESCRIPTION:Speakers: MROCZKOWSKI\, Tony ()\nhttps://events.mpifr-bonn.mpg .de/indico/event/58/session/12/contribution/52 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/12/contributi on/52 END:VEVENT BEGIN:VEVENT SUMMARY:Gas and dust masses of a star forming cloud DTSTART;VALUE=DATE-TIME:20180313T082000Z DTEND;VALUE=DATE-TIME:20180313T084000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-24@cern.ch DESCRIPTION:Speakers: LISEAU\, Rene ()\nWe have obtained both continuum an d spectral line maps with APEX.

We collected an extens ive dataset comprising multiple submillimeter spectral lines from neutral and ionized carbon and from CO. Based on it\, we aim to understand M8’s morphology and that of its associated photo dissociation region and to car ry out a quantitative analysis of the regions’ physical conditions such as kinetic temperatures and volume densities. Using the Stratospheric Obse rvatory For Infrared Astronomy (SOFIA)\, the Atacama Pathfinder Experiment (APEX) 12 m and the Institut de Radioastronomie Millimétrique (IRAM) 30 m telescopes\, we have performed a comprehensive imaging survey of the emi ssion from the fine structure lines of [CII] and [CI] and multiple rotatio nal transitions of carbon monoxide (CO) isotopologues within 1.3 × 1.3 pc around the dominant Herschel 36 (Her 36) system composed of at least thre e massive stars.

With an aim of providing insights into how high-mass star s form and interact with the surrounding ISM\, we have recently performed APEX observations of the [CI] 492 GHz fine-structure line for a representa tive sample of high-mass star-forming regions in the Galaxy (including ~40 IR-dark sources\, ~50 IR-bright sources\, and ~10 HII regions). The [CI] line is well detected from all but one of the target clouds\, demonstratin g APEX as an excellent instrument to study the neutral ISM at sub-millimet er wavelengths. Our preliminary analysis suggests that various populations of high-mass star-forming regions have systematically different propertie s of [CI] emission\, e.g.\, ~60%\, ~80%\, and ~100% of the IR-dark\, IR-br ight\, and HII region sources have the [CI] integrated intensity higher th an 10 K km/sec (median of all sample clouds). In the future\, our [CI] obs ervations will be combined with available multi-transition CO data\, as we ll as upcoming SOFIA [CII] 158 micron observations\, enabling us to examin e the physical\, chemical\, and energetic conditions of the carbon-traced ISM across evolutionary stages of high-mass star formation.\n\nhttps://eve nts.mpifr-bonn.mpg.de/indico/event/58/session/8/contribution/26 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/26 END:VEVENT BEGIN:VEVENT SUMMARY:CO and fine structure line cooling in NGC3603 and M17 DTSTART;VALUE=DATE-TIME:20180313T092000Z DTEND;VALUE=DATE-TIME:20180313T094000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-27@cern.ch DESCRIPTION:Speakers: PEREZ-BEAUPUITS\, Juan-Pablo ()\nMassive star formin g regions like the Giant Nebula NGC 3603 in the constellation Carina\, are ideal sources to study the clumpy structure of molecular clouds\, as well as the chemical and thermodynamic effects of the nearby ionising sources. Studies in the last decades have revealed NGC3603's hidden nature as the Milky Way’s most active stellar nursery. Maps of both [O I] 63 and 145 m icrons fine structure lines\, one of the most important cooling lines of t he ISM with a not fully understood role in the process of star formation\, were recently obtained with SOFIA/upGREAT toward NGC 3603. I will present analysis of the distribution and excitation of the [O I] lines\, combined with the CO SLED obtained with APEX and SOFIA/GREAT. A comparison with th e [O I] line and excitation of M17 SW will also be presented. The role of the [O I] lines in the process of star formation will be addressed.\n\nhtt ps://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contribution/27 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/27 END:VEVENT BEGIN:VEVENT SUMMARY:Mass-size scaling of ATLASGAL protocluster clumps -- theory surviv es the reality DTSTART;VALUE=DATE-TIME:20180312T160000Z DTEND;VALUE=DATE-TIME:20180312T162000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-20@cern.ch DESCRIPTION:Speakers: LI\, Guang-Xing ()\nObservations of ATLASGAL protocl uster clumps found that the masses and sizes of star clusters in the Milky Way are correlated where m_cluster ~ r_cluster ^ 1.67. We analytically st udy the interplay between turbulence and gravity in the molecular ISM\, an d found that structures that can dynamically detach from the ambient mediu m and collapse should obey m ~ r ^ 5/3. The normalisation of the scaling i s determined by the level of the ambient turbulence. The theoretical scali ng relation predicts the observations to a good accuracy. This is one inte resting case where the development of a theory is directly inspired by res ults observations of a large sample of objects carried out directly with t he APEX telescope.\n\nhttps://events.mpifr-bonn.mpg.de/indico/event/58/ses sion/8/contribution/20 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/20 END:VEVENT BEGIN:VEVENT SUMMARY:SPARKS: The search for high-mass protostars with ALMA up to kilo-p arsec scales DTSTART;VALUE=DATE-TIME:20180312T162000Z DTEND;VALUE=DATE-TIME:20180312T164000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-21@cern.ch DESCRIPTION:Speakers: CSENGERI\, Timea ()\nThe origin of the highest mass stars is still an enigma in modern astrophysics. Only massive clumps\, at the onset of star formation\, can reveal the initial conditions and shed l ight on the necessary physical processes leading to their formation. From the 870 micron ATLASGAL survey of the inner Galaxy\, we identified the com plete sample of infrared quiet massive clumps located closer than 5 kpc. W e targeted this sample in the frame of the SPARKS project with ALMA\, reac hing the physical scales of individual collapsing envelopes. This survey r eveals a large sample of high-mass protostellar fragments\, including youn g\, emerging hot-cores. In addition\, we find a handful of objects that ar e promising candidates for the rare high-mass pre-stellar cores. I discuss here the statistical results of this survey\, and show a case study of on e of the targets which reveals a ~100 Msol protostellar envelope that stay s single down to our resolution limit of 400 au.\n\nhttps://events.mpifr-b onn.mpg.de/indico/event/58/session/8/contribution/21 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/21 END:VEVENT BEGIN:VEVENT SUMMARY:ISM properties of a Massive Dusty Star-Forming Galaxy discovered a t z=7 DTSTART;VALUE=DATE-TIME:20180314T090000Z DTEND;VALUE=DATE-TIME:20180314T092000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-48@cern.ch DESCRIPTION:Speakers: STRANDET\, Maria ()\nI will present the discovery of the highest-redshift millimeter-selected dusty star-forming galaxy to dat a\, SPT0311-58\, at z = 6.900(2). SPT0311-58 was discovered via its 1.4 mm thermal dust continuum emission in the South Pole Telescope (SPT)-SZ surv ey. The spectroscopic redshift was determined through an ALMA 3mm frequenc y scan that detected CO(6-5)\, CO(7-6)\, and [CI](2-1)\, and subsequently was confirmed by detections of [CII] with APEX and CO(3-2) with ATCA. We c onstrain the properties of the ISM in SPT0311-58 with a radiative transfer analysis of the dust continuum photometry and the CO and [CI] line emissi on. This allows us to determine the gas content without ad hoc assumptions about gas mass scaling factors. We find that SPT0311-58 is extremely mass ive and its large mass and intense star formation is very rare for a sourc e well into the epoch of reionization.\n\nhttps://events.mpifr-bonn.mpg.de /indico/event/58/session/11/contribution/48 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contributi on/48 END:VEVENT BEGIN:VEVENT SUMMARY:Synergy between APEX and 4GREAT at SOFIA DTSTART;VALUE=DATE-TIME:20180314T095000Z DTEND;VALUE=DATE-TIME:20180314T101000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-49@cern.ch DESCRIPTION:Speakers: DURAN\, Carlos ()\n4GREAT extended the frequency cov erage of GREAT\, including 2 submm bands (500 GHz and 1THz)\, being these complementary to those covered already by APEX instrumentation.\n\nhttps:/ /events.mpifr-bonn.mpg.de/indico/event/58/session/12/contribution/49 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/12/contributi on/49 END:VEVENT BEGIN:VEVENT SUMMARY:Unveiling dust emission associated with an enormous Lyman-Alpha ne bula DTSTART;VALUE=DATE-TIME:20180314T082000Z DTEND;VALUE=DATE-TIME:20180314T084000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-46@cern.ch DESCRIPTION:Speakers: ARRIGONI BATTAIA\, Fabrizio ()\nIn the hierarchical model of structure formation\, giant elliptical galaxies form through merg ing processes\, within the highest density peaks known as protoclusters. U sually\, radio galaxies pinpoint the location of these young protoclusters . However\, as part of a campaign to map Lyman-alpha around several radio- quiet quasars\, we have discovered three giant (>250 kpc) nebulae that hos t multiple AGN and are surrounded by overdensities of Lyman-alpha emitters . These regions are prime candidates for massive protoclusters in the earl y stages of assembly. To search for ultraluminous starburst activity withi n these unique structures\, we have initiated a submm programme with singl e-dish telescopes\, including APEX. Intriguingly\, our first targeted larg e-scale structure at z=3.167 showed strong emission at 870 micron as seen with LABOCA. In this talk\, I will present these observations and discuss them also in light of the follow-up observations with SMA. I will conclude the talk by discussing the synergy between our APEX observations and our awarded project on ALMA for the same target.\n\nhttps://events.mpifr-bonn. mpg.de/indico/event/58/session/11/contribution/46 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contributi on/46 END:VEVENT BEGIN:VEVENT SUMMARY:Proto cluster formation at z=4 revealed by APEX and ALMA DTSTART;VALUE=DATE-TIME:20180314T084000Z DTEND;VALUE=DATE-TIME:20180314T090000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-47@cern.ch DESCRIPTION:Speakers: WEIß\, Axel ()\nhttps://events.mpifr-bonn.mpg.de/in dico/event/58/session/11/contribution/47 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contributi on/47 END:VEVENT BEGIN:VEVENT SUMMARY:Excess of Dusty Starbursts at z=2 DTSTART;VALUE=DATE-TIME:20180313T172000Z DTEND;VALUE=DATE-TIME:20180313T174000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-44@cern.ch DESCRIPTION:Speakers: DANNERBAUER\, Helmut ()\nA prominent feature of colo ur-magnitude diagrams of (local) clusters is the often so-called red seque nce. These red-sequence galaxies are dominating the core of the galaxy clu sters and their members are massive\, early-type galaxies. Distant dusty s tarbursts with short time scales of building up the bulk of their stellar mass are promising candidates for being the ancestors of red sequence gala xies. Thus\, searching for massive\, dusty star-forming galaxies offers a great opportunity to trace galaxy overdensities and therefore the cosmic w eb in the early universe. With APEX-LABOCA\, we have targeted several know n (proto)cluster fields. We focus on the protocluster field of the radio g alaxy MRC1138-262 where have uncovered an excess of submillimeter galaxies . Based on this initial discovery\, we have conducted extensive observing campaigns of the cold interstellar medium - dust and molecular gas - of se veral submm bright cluster members with ALMA and the Australian Telescope Compact Array. The presented study enables us to investigate the environme ntal dependency of the amount of cold molecular gas\, the star formation e fficiency and the formation of red-sequence galaxies. Finally\, I will dis cuss the potential of revealing (proto)clusters of massive\, dusty starbur sts with the upcoming new APEX capabilities.\n\nhttps://events.mpifr-bonn. mpg.de/indico/event/58/session/11/contribution/44 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contributi on/44 END:VEVENT BEGIN:VEVENT SUMMARY:Fine-structure lines in dusty star-forming galaxies from SPT DTSTART;VALUE=DATE-TIME:20180313T164000Z DTEND;VALUE=DATE-TIME:20180313T170000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-42@cern.ch DESCRIPTION:Speakers: DE BREUCK\, Carlos ()\nFar-IR fine-structure lines ( FSL) are powerful probes of the Physical conditions in the ISM\, such as t he density\, ionization mechnanism\, and metallicity. They have been mostl y studied in the optical\, but this has the disadvantage that they can be significantly obscured. The rest-frame far-IR FSL are mostly unobscured\, and are redshifted into several of the SEPIA and FLASH bands.

When coupled with high-J CO emission lines the ratio\, high-J CO/CI\, is a good proxy of (warm\, dense\, star-forming (SF) gas)/(total H2 gas) mas s fraction and provides a unique insight on the main source heating the ga s and therefore indicating whether a system is merger driven or disc-like.

Combining this sample {with} our recent new Valpara\\'iso ALMA Line Emission Survey (VALES)\, we investigat e the star formation efficiencies (SFEs = SFR/MH2) of galaxies at low reds hift. We find the SFE of our sample bridges the gap between normal star-fo rming galaxies and Ultra-Luminous Infrared Galaxies (ULIRGs)\, which are t hought to be triggered by different star formation modes. Considering the SFE′ as the SFR and the L′CO ratio\, our data show a continuous and sm ooth increment as a function of infrared luminosity (or star formation rat e) with a scatter about 0.5 dex\, instead of a steep jump with a bimodal b ehaviour. This result is due to the use of a sample with a much larger ran ge of sSFR/sSFRms using LIRGs\, with luminosities covering the range betwe en normal and ULIRGs. We conclude that the main parameters controlling the scatter of the SFE in star-forming galaxies are the systematic uncertaint y of the αCO conversion factor\, the gas fraction and physical size.\n\nh ttps://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contribution/41 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contributi on/41 END:VEVENT BEGIN:VEVENT SUMMARY:Announcements DTSTART;VALUE=DATE-TIME:20180312T081000Z DTEND;VALUE=DATE-TIME:20180312T081500Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-1@cern.ch DESCRIPTION:Speakers: WYROWSKI\, Friedrich ()\nhttps://events.mpifr-bonn.m pg.de/indico/event/58/contribution/1 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/contribution/1 END:VEVENT BEGIN:VEVENT SUMMARY:Welcome DTSTART;VALUE=DATE-TIME:20180312T080000Z DTEND;VALUE=DATE-TIME:20180312T081000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-0@cern.ch DESCRIPTION:Speakers: MENTEN\, Karl ()\nhttps://events.mpifr-bonn.mpg.de/i ndico/event/58/contribution/0 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/contribution/0 END:VEVENT BEGIN:VEVENT SUMMARY:Summary DTSTART;VALUE=DATE-TIME:20180314T111000Z DTEND;VALUE=DATE-TIME:20180314T113000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-3@cern.ch DESCRIPTION:Speakers: \nhttps://events.mpifr-bonn.mpg.de/indico/event/58/c ontribution/3 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/contribution/3 END:VEVENT BEGIN:VEVENT SUMMARY:Castle tour DTSTART;VALUE=DATE-TIME:20180312T170000Z DTEND;VALUE=DATE-TIME:20180312T180000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-2@cern.ch DESCRIPTION:Speakers: \nhttps://events.mpifr-bonn.mpg.de/indico/event/58/c ontribution/2 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/contribution/2 END:VEVENT BEGIN:VEVENT SUMMARY:The APEX upgrade DTSTART;VALUE=DATE-TIME:20180312T083500Z DTEND;VALUE=DATE-TIME:20180312T085500Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-5@cern.ch DESCRIPTION:Speakers: GÜSTEN\, Rolf ()\nhttps://events.mpifr-bonn.mpg.de/ indico/event/58/session/5/contribution/5 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/5/contributio n/5 END:VEVENT BEGIN:VEVENT SUMMARY:Status of APEX DTSTART;VALUE=DATE-TIME:20180312T081500Z DTEND;VALUE=DATE-TIME:20180312T083500Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-4@cern.ch DESCRIPTION:Speakers: NYMAN\, Lars-Ake ()\nhttps://events.mpifr-bonn.mpg.d e/indico/event/58/session/5/contribution/4 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/5/contributio n/4 END:VEVENT BEGIN:VEVENT SUMMARY:APEX 2 Science Operations : 2018 and beyond DTSTART;VALUE=DATE-TIME:20180312T091500Z DTEND;VALUE=DATE-TIME:20180312T093500Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-7@cern.ch DESCRIPTION:Speakers: MONTENEGRO\, Francisco ()\nWith the refurbished APEX and the new suite of state-of-the-art facility instrumentation\, includin g high frequency facility B9 channel\, new challenges open up for science operations.

To reach that goal\, we propose to constru ct a spectrometer to map in three dimensions the specific intensity due to line emission\, a technique known as "Intensity Mapping". Our experiment is capitalizing on the recent technology breakthrough that our team obtain ed on the development of large KID (Kinetic Inductance Detectors) instrume nts like NIKA2 at the IRAM 30-meters telescope. From the technological poi nt-of-view\, CONCERTO will represent to our knowledge the first implementa tion of multi-thousands spectro-imaging pixels at millimeter and sub-milli meter wavelengths. We propose to implement around 3\,000 KID detectors to image an instantaneous field-of-view of 12 to 15 arc-minutes in diameter\, with an angular resolution of the order of 20 arc-seconds. Each detector will be able to acquire between 2 and 10 spectra per second with a spectra l resolution R=lambda/Delta_lambda=100-200 and spanning the range 200-360G Hz\, ideally accessible from APEX. CONCERTO will thus\, from the read-out and data analysis point-of-view\, be the equivalent of a pure imager conta ining 3E5 detectors. The high-speed\, i.e. above the typical atmospheric 1 /f corner\, Fourier interferometry technique is possible only thanks to th e fast response time of the KID compared to the competing bolometers. I wi ll describe the instrument design and present preliminary results obtained during the development of the CONCERTO pathfinder named KISS. The pathfin der will be installed by the end of 2018 in Tenerife on the QUIJOTE telesc ope and will be dedicated to observe low-redshift galaxies clusters via th e SZ (Sunyaev-Zel'dovich) effect.\n\nhttps://events.mpifr-bonn.mpg.de/indi co/event/58/session/6/contribution/13 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/6/contributio n/13 END:VEVENT BEGIN:VEVENT SUMMARY:The gas phase carbon budget in low-metallicity star-forming region s DTSTART;VALUE=DATE-TIME:20180313T152000Z DTEND;VALUE=DATE-TIME:20180313T154000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-38@cern.ch DESCRIPTION:Speakers: RUBIO\, Monica ()\nhttps://events.mpifr-bonn.mpg.de/ indico/event/58/session/11/contribution/38 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contributi on/38 END:VEVENT BEGIN:VEVENT SUMMARY:ArTéMiS: status\, performances and upgrades DTSTART;VALUE=DATE-TIME:20180312T111000Z DTEND;VALUE=DATE-TIME:20180312T113000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-11@cern.ch DESCRIPTION:Speakers: REVERET\, Vincent ()\nThe ArTéMiS submillimeter cam era has been regularly used for science since 2013 at APEX.

In normal ga laxies following the so-called ‘main sequence’ of star-forming galaxie s\, the star formation rate is believed to be regulated uniquely by the am ount of gas available\, and more specifically by the mass of cold and dens e molecular gas. Despite the enormous efforts to trace molecular gas in la rger and larger samples of galaxies\, at multiple scales and at multiple e pochs\, nearly all of our empirical knowledge of scaling relations linking molecular gas and galaxy properties is still based on observations of loc al massive (e.g. M*>10^10 M_Sun)\, metal-rich and gas-rich spirals. There is therefore a strong motivation to test molecular gas scaling relations o ver a much broader dynamic range of galaxy properties. With this goal in m ind\, we have undertaken the “APEX low-redshift legacy survey of molecul ar gas (ALLSMOG)”\, an ESO large programme (>300h) to survey the CO(2-1) line emission in a sample of ~100 normal star forming galaxies in the loc al Universe\, characterised by stellar masses (10^8.5\n\nhttps://events.mp ifr-bonn.mpg.de/indico/event/58/session/11/contribution/39 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/11/contributi on/39 END:VEVENT BEGIN:VEVENT SUMMARY:ZEUS-2 on APEX DTSTART;VALUE=DATE-TIME:20180312T130000Z DTEND;VALUE=DATE-TIME:20180312T132000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-12@cern.ch DESCRIPTION:Speakers: STACEY\, Gordon ()\nI will present the current statu s and latest science results obtained with our submillimeter grating spect rometer\, ZEUS-2 on APEX.

In the Milky Way a si ngle value is used at all galactocentric radii\, independently of the obse rved metallicity gradients. Both models and extragalactic observations sug gest that this quantity increases for decreasing metallicity Z\, typical o f the outer regions in disks\, where fewer heavy elements are available to form dust grains. We investigate the radial variation of the gas-to-dust ratio in the Milky Way disc by comparing estimates of this parameter in a sample of 23 massive and dense clumps in the far outer Galaxy (R_gc > 14 k pc) with those obtained for the ATLASGAL TOP100 sample. Using the metallic ity gradients derived from Cepheids\, we additionally connect the variatio n of the gas-to-dust ratio to Z\, finding that the gas-to- dust ratio incr eases as Z to the power -1.4. This indicates that grain growth dominates o ver destruction\, and is the most common situation in late-type galaxies l ike the MW. Our results are also in excellent agreement with recent estima tes of the gas-to-dust ratio in the Magellanic Clouds.\n\nhttps://events.m pifr-bonn.mpg.de/indico/event/58/session/8/contribution/23 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/23 END:VEVENT BEGIN:VEVENT SUMMARY:Synergies with the SMA & ACA DTSTART;VALUE=DATE-TIME:20180314T103000Z DTEND;VALUE=DATE-TIME:20180314T105000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-51@cern.ch DESCRIPTION:Speakers: BLUNDELL\, Raymond ()\nhttps://events.mpifr-bonn.mpg .de/indico/event/58/session/12/contribution/51 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/12/contributi on/51 END:VEVENT BEGIN:VEVENT SUMMARY:Large scale CO observations in the CMZ DTSTART;VALUE=DATE-TIME:20180313T142000Z DTEND;VALUE=DATE-TIME:20180313T144000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-36@cern.ch DESCRIPTION:Speakers: RIQUELME\, Denise ()\nhttps://events.mpifr-bonn.mpg. de/indico/event/58/session/10/contribution/36 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/10/contributi on/36 END:VEVENT BEGIN:VEVENT SUMMARY:New insights into the CMZ with SEDIGISM and ArTeMiS DTSTART;VALUE=DATE-TIME:20180313T140000Z DTEND;VALUE=DATE-TIME:20180313T142000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-35@cern.ch DESCRIPTION:Speakers: SCHULLER\, Frederic ()\nAfter a general description of the SEDIGISM survey (Structure\, Excitation and Dynamics of the Inner G alactic ISM) and an overview of the first results obtained\, I will focus on the Galactic Central Molecular Zone.

Their interaction with the ISM can cause interstellar turbulence and drive gala ctic outflows. Our understanding of the interaction of an SNR with a molec ular cloud (MC) is limited due to the paucity of known sources and observe d molecules. In this project we have carried out sub-millimeter observatio ns of the well known SNR W28 using the APEX telescope to probe the post-sh ock conditions in an SNR-MC interaction region. Such a study sheds light o n the molecular complexity found in these regions and helps us to understa nd how the SNR-MC interactions modify the physical conditions and conseque ntly the chemistry of the ISM. In our observations\, we have have found ro tational lines of multiple species including CH3OH\, H2CO and SO. In this talk we will have a look at the results of this study and the various meth ods used to constraint the physical conditions in the interaction region.\ n\nhttps://events.mpifr-bonn.mpg.de/indico/event/58/session/9/contribution /34 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/9/contributio n/34 END:VEVENT BEGIN:VEVENT SUMMARY:Colliding winds from massive stars DTSTART;VALUE=DATE-TIME:20180313T132000Z DTEND;VALUE=DATE-TIME:20180313T134000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-33@cern.ch DESCRIPTION:Speakers: SETIA GUNAWAN\, Diah ()\nhttps://events.mpifr-bonn.m pg.de/indico/event/58/session/9/contribution/33 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/9/contributio n/33 END:VEVENT BEGIN:VEVENT SUMMARY:Lessons from the Galactic center to the interpretation of extragal actic C+ observations as tracers of star formation DTSTART;VALUE=DATE-TIME:20180313T144000Z DTEND;VALUE=DATE-TIME:20180313T150000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-37@cern.ch DESCRIPTION:Speakers: HARRIS\, Andrew ()\nhttps://events.mpifr-bonn.mpg.de /indico/event/58/session/10/contribution/37 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/10/contributi on/37 END:VEVENT BEGIN:VEVENT SUMMARY:The kinematics of dust detected filaments DTSTART;VALUE=DATE-TIME:20180312T152000Z DTEND;VALUE=DATE-TIME:20180312T154000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-18@cern.ch DESCRIPTION:Speakers: MATTERN\, Michael ()\nhttps://events.mpifr-bonn.mpg. de/indico/event/58/session/8/contribution/18 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/8/contributio n/18 END:VEVENT BEGIN:VEVENT SUMMARY:Synergies and complementarities between SOFIA and APEX DTSTART;VALUE=DATE-TIME:20180314T101000Z DTEND;VALUE=DATE-TIME:20180314T103000Z DTSTAMP;VALUE=DATE-TIME:20260717T231307Z UID:indico-contribution-58-50@cern.ch DESCRIPTION:Speakers: SANDELL\, Göran ()\nIn this talk I review synergies and complementarities between SOFIA and APEX\, both in terms of instrumen t suites and science capabilities.\n\nhttps://events.mpifr-bonn.mpg.de/ind ico/event/58/session/12/contribution/50 LOCATION:Schloss Ringberg URL:https://events.mpifr-bonn.mpg.de/indico/event/58/session/12/contributi on/50 END:VEVENT END:VCALENDAR
