AGN feedback using AMR cosmological simulations
  Feedback processes are thought to solve some of the long-standing issues of
the numerical modelling of galaxy formation: over-cooling, low angular
momentum, massive blue galaxies, extra-galactic enrichment, etc. The accretion
of gas onto super-massive black holes in the centre of massive galaxies can
release tremendous amounts of energy to the surrounding medium. We show, with
cosmological Adaptive Mesh Refinement simulations, how the growth of black
holes is regulated by the feedback from Active Galactic Nuclei using a new dual
jet/heating mechanism. We discuss how this large amount of feedback is able to
modify the cold baryon content of galaxies, and perturb the properties of the
hot plasma in their vicinity.
