Abstract |
The spatial distribution of matter in clusters of galaxies is mainly determined by the dominant dark matter component, however, physical processes involving baryonic matter are able to modify it significantly. We analyse a suite of cosmological hydrodynamical simulations of a Virgo-like cluster of galaxies, performed using the AMR code RAMSES. We show that the inclusion of super massive black holes and active galactic nuclei feedback significantly modifies the star formation properties, the central galaxy properties and the total mass distribution. In particular, at redshift z=0 we find a flat density core of radius 10 kpc in both of the dark and stellar matter density profiles. |
