About SRGSRG is a joint Russian - German mission launched from the Baikonur, Kazakhstan, Cosmodrome 13 July 2019. SRG's main scientific goal is to chart an unprecedented map of the Universe in X-rays on which all large clusters of galaxies will be marked. Spektr-RG is expected to find about 100,000 massive clusters of galaxies during the four-year survey mode, which means literally all such objects in the observable Universe. Furthermore, it will detect around three million supermassive black holes in active galactic nuclei (AGN), along with hundreds of thousands of stars with active coronae and accreting white dwarfs, tens of thousands of galaxies with active star formation. The main scientific goals of Spectr-RG are:
About eROSITAeROSITA (extended ROentgen Survey with an Imaging Telescope Array) is a sensitive X-ray telescope capable of delivering deep, sharp images over very large areas of the sky in the energy range ~0.2-8 keV. More details can be found at the eROSITA-DE science portal. Publications and additional information
About ART-XCThe ART-XC instrument is an array of seven nearly identical, co-aligned, X-ray grazing incidence mirror telescopes developed by the Russian Space Research Institute (IKI) and the All-Russian Scientific Research Institute for Experimental Physics (VNIIEF). NASA's Marshall Space Flight Center (MSFC) developed, fabricated, and calibrated the X-ray mirrors. ART-XC is providing the first-ever high spatial resolution survey of the sky in the 4-30 keV hard X-ray energy range. Additional information can be found at the NASA MSFC ART-XC site.
