Two years of eROSITA all-sky surveys: The variable X-ray sky

The eROSITA telescope onboard the SRG satellite was launched on 13 July 2019. After an initial phase of calibration and performance verification observations eROSITA started its all-sky survey operation in December 2019. Covering the entire sky within 6 months, eROSITA is now close to completing its 4th all-sky survey in the 0.2-10 keV band. With the repeated detection of about 1 Million sources in each of the surveys, the eROSITA surveys are a particularly rich resource for the study of variable X-ray sources.
I will report on selected highlights of the mission such as an accurate distance measurement towards a Black Hole candidate using dust scattering, the observation of isolated neutron stars, or of galaxies caught in the moment of ignition or shut-down of their active nuclei.
