SRG/eRosita: X-ray map of the whole sky. Some results of the first all-sky survey and plans for the future
Speaker:
Abstract:
Spektr-RG spacecraft with Russian (ART-XC) and German (eRosita) X-Ray telescopes was launched on July 13th of 2019 from Baykonur. During the flight to the L2 point of the Sun-Earth system, SRG performed calibrations and detailed long duration Performance Verification (PV) observations of more than a dozen of targets. Starting in the middle of December 2019, the SRG Observatory scanned the whole sky in half a year and discovered more than a million point X-Ray sources, mainly AGNs and QSOs, stars with hot and bright coronae, and more than 16 thousand clusters of galaxies. SRG provided the X-Ray map of the whole sky in hard and soft bands, which is now the best among existing. It reveals a lot of information about the distribution of absorbing gas in the Milky Way and provides a beautiful image of the North Polar Spur and similar bright emitting feature on another side from the Central Part of the Galaxy. I plan to describe the Observatory plans for the future and to demonstrate several exciting results from the PV phase observations as well as from the second all-sky survey which is ongoing.
