Title: Faint high-redshift AGN: the evolution of the AGN luminosity function and black hole demography
Date: Wednesday, December 14th, 2011
Time: 15:00
Venue: Villa Bazzoni

Abstract:
I will present a pilot program to push the search of normal, L*AGN up to z=5-6, and discuss the
astrophysical and cosmological perspectives of this line of research.
Targeting high-z black holes, the structures with the fastest (exponential)
growth rate, can help investigating the evolution of the Universe at those
early epochs, because little differences in the time of expansion of the Universe
can be significantly emphasized. By comparing the high-z SMBH mass function to model predictions we might on
one side disentangle competing cosmological scenarios, and on the other side
put constraints on the physics of accretion and AGN triggering
mechanisms at high-redshift.
