Quantifying the effect of black hole feedback from the central galaxy on
  the satellite populations of groups and clusters
  Super-massive black holes are fundamental ingredients in our theoretical
understanding of galaxy formation. They are likely the only sources energetic
enough to regulate star formation within massive dark matter halos, but
observational evidence of this process remains elusive. The effect of black
hole feedback is expected to be a strong function of halo mass, and galaxy
groups and clusters are among the most massive structures in the Universe. At
fixed halo mass, we find an enhanced fraction of quiescent satellite galaxies
and a hotter X-ray intragroup and intracluster medium in those groups and
clusters hosting more massive black holes in their centers. These results
indicate that black hole feedback makes quenching processes more efficient
through a cumulative heating of the gaseous intragroup and intracluster medium.
