eROSITA Science Book: Mapping the Structure of the Energetic Universe

Understand

eROSITA is the primary instrument on the Russian SRG mission.

• In the first four years of scientific operation after its launch, foreseen for 2014, it will perform a deep survey of the entire X-ray sky.
• In the soft X-ray band (0.5-2 keV), this will be about 20 times more sensitive than the ROSAT all sky survey, while in the hard band (2-10 keV) it will provide the first ever true imaging survey of the sky at those energies.
• Such a sensitive all-sky survey will revolutionize our view of the high-energy sky, and calls for major efforts in synergic, multi-wavelength wide area surveys in order to fully exploit the scientific potential of the X-ray data.
