Today's colloquium: eROSITA - The Next X-ray All Sky Survey
| Submitter: | Joern Wilms |
| Description: | The X-rays are amongst the wavebands where the sky is least well known. There exists only one shallow survey, made by the ROSAT satellite in the 1990s in the soft X-rays. This will change with the launch in March 2019 of the German eROSITA experiment on the Russian satellite Spectrum-X-Gamma. eROSITA will perform a four year long survey of the X-ray sky at energies up to 10keV, discovering a million new Active Galaxies, 100000 galaxy clusters, and a large number of other objects. In my talk I will summarize the scientific aims of eROSITA, describe the technology to be used, and I will discuss the use of the eROSITA in the context of other all sky surveys that will become available in the 2020s.
