SUMMARY:Mapping the hot Universe: the first six months of operations of eR
 OSITA on SRG - Andrea Merloni (MPE)

DESCRIPTION:The emergence of the three-dimensional structure of the cosmic
  web over the history of the Universe displays very distinctive features w
 hen observed in X-rays\, where both the most massive collapsed structure (
 clusters of galaxies) and the most energetic events in the life of galaxie
 s (AGN and Quasars) reveal themselves unambiguously. The next generation o
 f wide-area\, sensitive X-ray surveys designed to map the hot and energeti
 c Universe will be heralded by eROSITA (extended ROentgen Survey with an I
 maging Telescope Array)\, the core instrument on the Russian-German Spektr
 um-Roentgen-Gamma (SRG) mission\, successfully launched in July 2019. On D
 ecember 13\, after completion of its Calibration and Performance Verificat
 ion phase\, SRG/eROSITA has begun its four-years program dedicated to surv
 eying the entire sky eight times in the energy range ~0.2-8 keV. The high 
 sensitivity\, large field of view\, high spatial resolution and high surve
 y efficiency of eROSITA is bound to revolutionize X-ray astronomy: within 
 just the first year of operation it will discover more new celestial X-ray
  objects than have been catalogued from 1962 until today. I will present a
 n overview of the instrument capabilities\, the current status of the miss
 ion\, the early science results and the expectations for the X-ray all-sky
  survey program and its planned followup programs.
