eROSITA ( e xtended RO entgen S urvey with an I maging T elescope A rray ) is a satellite - bound X - ray telescope , which is supposed to examine the universe in the range from 0.3 to 11 keV in a new spectral and spatial resolution. It was developed at the Max Planck Institute for Extraterrestrial Physics in collaboration with institutes in Bamberg, Hamburg, Potsdam and Tübingen. The entire project will cost around 90 million euros, of which DLR and MPE will each bear around half.
aims
The scientific goals are the systematic detection of black holes in nearby galaxies and of over three million distant active galaxies as well as the detection of hot intergalactic gas in 50,000-100,000 galaxy clusters and groups in order to gain knowledge about the large-scale structure of the cosmos and its development . In addition, detailed studies of the physical nature of galactic X-ray sources such as supernova remnants or X-ray binary stars are carried out. The data obtained are also intended to enable new scientific knowledge regarding dark matter and dark energy . This hypothetical form of energy is one possible explanation for the observation that the universe is still expanding at an accelerated rate; it is therefore related to some of the most exciting questions in astronomy and physics.
Mission history
eROSITA is part of the Russian-German space observatory Spektr-RG (short for Spectrum-X-Ray-Gamma), which was launched into space on July 13, 2019 with a Proton rocket . Spectrum-RG was positioned in a halo orbit around the Lagrange point L 2 of the earth-sun system, from where eROSITA is to scan the entire sky eight times within four years.
The first full survey was completed one year after launch. It lasted 182 days and 165 gigabytes of data were collected. From this, a map with around one million X-ray objects was created.
