eROSITA cosmology with galaxy groups: hot gas budget out to the virial radius
Non-gravitational processes that expel hot gas beyond the virial regions of groups and clusters of galaxies, known collectively as baryonic feedback, play a key role in reshaping the matter distribution of the Universe on Mpc scales.
