Dissecting the Universe - Workshop on Results from High-Resolution VLBI
<p><img alt="" src="https://events.mpifr-bonn.mpg.de/indico/event/4/material/0/0.png" style="height:430px; width:720px" /></p>
<p><strong>Scientific rationale:</strong></p>
<p>Recent developments have pushed the limits of resolution in astrophysics to new frontiers. Very-long-baseline interferometry (VLBI) at millimetre wavelengths or using antennas in space yields resolutions down to tens of microarcseconds (that is, fractions of nanoradians). These observations probe compact objects such as the innermost regions of active galactic nuclei. Space VLBI is living a new era at present with the results from the RadioAstron mission, enhancing radio interferometry in terms of resolution at least one order of magnitude with respect to ground-based VLBI. Millimetre VLBI also brings radio interferometry to a new range of resolution and with much enhanced sensitivity due to improvements in data bit rate. With more antennas capable of VLBI at 3-mm wavelength, and successful observations being carried out at 1-mm, a new window is open to universe at unprecedented resolution. This workshop will review recent results on high resolution radio astronomy, including opportunities provided by new antennas becoming available. It will also discuss on the applications of high-resolution imaging techniques and the synergies in the study of compact objects by space and mm-VLBI together. </p>
<p>Contributions to the workshop will be published online in this webpage; no regular proceedings are planned. Abstracts will be sent to the Astrophysical Data System.</p>

The RadioAstron AGN survey is performed by the space radio telescope Spektr-R and many sensitive ground radio telescopes in Russia, Europe, Asia, USA, South Africa, Australia, Japan at 18, 6, and 1.3 cm and has already detected about 140 AGNs at projected spacings up to 27 Earth diameters. Formal resolution as high as 14 microarcsec has been achieved for AGNs observed at 22 GHz. Current status and results of the RadioAstron AGN survey program will be summarized including statistics of measurements of very high brightness temperatures in AGN cores and physical implications of these findings. <p>
