The M*-Mhalo relation at 0.08 < z < 1.53 in COSMOS: the role of AGN
  radio-mode feedback
  In the current picture of cosmology and astrophysics, the formation and
evolution of galaxies is closely linked to that of their dark matter haloes.
The best representation of this galaxy-dark matter halo co-evolution is the M*
- Mhalo relation. In this study we investigate how the radio-mode feedback from
active galactic nuclei (AGN) affects the M* - Mhalo relation at redshifts 0.08
< z < 1.53. We use a set of 111 radio-selected AGN at 3 GHz VLA-COSMOS within
the X-ray galaxy groups in the COSMOS field. We compare these results to the
ones of 171 star-forming galaxies (SFGs), using the theoretical relation of
Moster et al. (2013). We find that AGN agree within 1% with the Moster et al.
(2013) relation, SFGs show an offset of 37%, suggesting that the radio-mode
feedback from AGN at a median redshift of ~ 0.5 still plays a significant role
in the M* - Mhalo relation.
