We consider simple semi-analytic models that relate the active galactic nuclei (AGNs) evolution to the merging history of their host dark matter haloes and quantify their ability of matching the AGN luminosity function (LF) and its spatial clustering at low and intermediate redshifts. In particular, we focus on the recent determinations of the...

We investigate the ability of hierarchical models of quasi-stellar object (QSO) formation and evolution to match the observed luminosity, number counts and spatial clustering of quasars at redshift z < 2. These models assume that the QSO emission is triggered by galaxy mergers, that the mass of the central black hole (BH) correlates with halo...
