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>

Despite numerous and detailed studies of the jets of Active Galactic Nuclei (AGN) on pc-scales, many questions are still debated. The physical nature of the jet-components is one of the most prominent unsolved problems as is the launching mechanism of jets in AGN. An in-depth investigation of long-term archival VLBI and multi-wavelength data (several decades) in combination with the application of theoretical models allows detailed studies of the overall properties of jets. This enables us to discriminate between motion scenarios and to derive a more physical understanding of the nature and and origin of jets in general. We will present and discuss recent results.<p>
