SRG spacecraft, carrying the eROSITA X-ray telescope, is scheduled for launch from Baikonur on Friday, June 21, at 15:17 EST.
The main scientific goals of eROSITA are:
- to detect the hot intergalactic medium of 50-100 thousand galaxy clusters and groups and hot gas in filaments between clusters to map out the large scale structure in the Universe for the study of cosmic structure evolution,
- to detect systematically all obscured accreting Black Holes in nearby galaxies and many (up to 3 Million) new, distant active galactic nuclei and
- to study in detail the physics of galactic X-ray source populations, like pre-main sequence stars, supernova remnants and X-ray binaries.
UT Tartu Observatory scientists are participating in the J-PAS project which complements the mission with ground observations.
