Abstract:
Clustering measurements has become one of the leading tools in cosmology
and theories of galaxy formation. In this work, we use clustering
measurements to constrain viable models of quasar activation and black
hole evolution. In particular, at high redshifts, observations indicate
that models with *short* time delays between the triggering of the
quasar and the peak of activity are preferred. Such a fast phase of
early accretion points to the possibility of either massive black hole
seeds, super-Eddington growth, or both. At low redshifts, we find a
rather strong clustering signal at all luminosities. These measurements
select models that place faint quasars in very massive dark matter
haloes. These type of studies will hopefully play an important role at
guiding the next generation of galaxy formation models.
