Description
About a year ago launched SRG carries eROSITA and ART-XC X-ray telescopes
on board and will contribute considerably to cosmology by investigating
cosmic large scale structure properties associated with galaxy clusters. Four years of data taking will allow to observe all the galaxy clusters formed in
the visible Universe. At the same time SRG can reveal the nature of Unknown Components of the present Universe by probing specific particle physics models of dark energy and dark matter. In particular, dark matter particles decaying (e.g. sterile neutrinos) or annihilating with keV-scale photons in the final state can be probed with eROSITA (energy range 0.2--10\,keV) and ART-XC (4--30\,keV)
X-ray telescopes aboard, including tests of the controversal 3.5keV line.
