SUMMARY:eROSITA: a global view of the hot Universe - Andrea Merloni\, MPE

DESCRIPTION:The emergence of the three-dimensional structure of the cosmic
  web\ndisplays distinctive features when observed in X-rays\, where both t
 he\nmost massive collapsed structure (clusters of galaxies) and the most\n
 energetic events in the life of galaxies (AGN and Quasars) reveal\nthemsel
 ves unambiguously.\nThe next generation of wide-area\, sensitive X-ray sur
 veys designed to\nmap the hot and energetic Universe will be heralded by e
 ROSITA (extended\nROentgen Survey with an Imaging Telescope Array)\, the c
 ore instrument on\nthe Russian Spektrum-Roentgen-Gamma (SRG) mission\, cur
 rently scheduled\nfor launch in 2016. eROSITA will perform a deep survey o
 f the entire\nX-ray sky\, and will be about 30 times more sensitive than R
 OSAT in the\nsoft energy band (0.5-2 keV)\, while in the hard band (2-8 ke
 V) it will\nprovide the first ever true imaging survey of the full sky.\nT
 he design driving science is the detection of large samples of galaxy\nclu
 sters to redshifts z~1\, in order to test cosmological models\nincluding D
 ark Energy. In addition\, eROSITA is expected to yield a\nsample of around
  3 million active galactic nuclei\, which is bound to\nrevolutionize our v
 iew of the evolution of supermassive black holes and\ntheir impact on the 
 process of structures and galaxy formation. The\nsurvey will also provide 
 new insights into a wide range of astrophysical\nphenomena\, including iso
 lated neutron stars\, X-ray binaries\, active\nstars and diffuse emission 
 from the hot plasma within the Galaxy\, as\nwell as more exotic ones such 
 as gamma-ray bursts\, tidal disruption of\nstars in galactic nuclei and bi
 nary black holes.\nIn this talk I will review the current mission status\,
  discuss the major\nscientific goals of the project\, and outline synergie
 s with\nmulti-wavelength wide area surveys\, in particular current and fut
 ure\ndedicated spectroscopic follow-up programs such as SDSS-IV/SPIDERS an
 d\nthe ESO/4MOST AGN and Clusters surveys.
