Please consider joining us at the Committee on Space Research (COSPAR) Scientific Assembly to be held in Sydney 15-22 August 2020 where we will be holding the Scientific Event E1.19: "<i>Scientific opportunities from multi-wavelength follow-up of large-area
X-ray surveys</i>" (see <a href="https://protect-au.mimecast.com/s/nCmwCOMxNytpprRDWhEltZh?domain=cospar-assembly.org" id="LPlnk758133">https://www.cospar-assembly.org/admin/session_cospar.php?session=906</a>). </div>

This event will be highly relevant for those that plan on making use of the collaborative agreement between Australian Astronomers and the German eROSITA consortium (<a href="https://protect-au.mimecast.com/s/m5zFCP7yOZtKKAGBpH0jXY1?domain=astronomyaustralia.org.au" id="LPNoLP743037">http://www.astronomyaustralia.org.au/erosita-collaboration.html</a>),
and also to those that responded to our recent call for Australia/eROSITA_DE collaborative projects.</div>

<i><span>"Wide area X-ray surveys reveal aspects of the Universe that are difficult or impossible to study at other wavelengths. They can be used to trace the large-scale structure via the distribution of hot gas in clusters and groups of galaxies, and determine
the underlying cosmology through its evolution. Growing supermassive black holes can be discovered over a broad redshift and luminosity range, outshining their host galaxies and penetrating through obscuring dust and gas. In our own Galaxy, active stellar
coronae shine brightly in the X-rays, as do accreting binary systems, displaying rich phenomenology which probe the nature of compact objects and the accretion processes which feed them. These binaries are often transient, as are other violent high energy
phenomena which can be observed over a range of timescales.<br>

<div><i>The pioneering work of the ROSAT all-sky survey, which provided the first true imaging survey over the whole sky, has been complemented more recently with a combination of dedicated wide field, archival serendipitous analysis, and slew surveys with
facilities such as XMM-Newton and Chandra. Most recently, the eROSITA and ART-XC instruments have been launched aboard the Spectrum-RG satellite in July 2019, ushering in a new era of wide field X-ray surveys, providing the natural succession to ROSAT all-sky
survey, but with much greater depth, image quality, and spectral coverage.<br>

<div><i><br>
</i></div>
<span><i>Follow-up observations at other wavebands are essential for full scientific exploitation of the X-ray data. A suite of wide-field surveys across a broad frequency range is now available for statistical study of large samples, as are sensitive new facilities
which can chase up interesting new objects and X-ray phenomena. This meeting will provide a forum to discuss these scientific opportunities, focussing particularly on the potential for new insights provided by eROSITA, working in concert with ground-based
facilities across other wavelengths." </i></span><br>
