Conclusions
ß SDSS is a tremendously powerful tool for studying the optical
properties of AGN at z=0 to z=6.5.
ß Luminous quasars peaked in comoving space density at z~2.5.
Luminosity function slope change is qualitatively consistent
with ‘cosmic downsizing’ picture.
ß At low redshifts, AGN luminosity function can be pushed
down to very low luminosities. Continuity with classical
quasars is work in progress.
ß Very luminous Type II quasars can be selected from the
SDSS spectroscopic sample, and studied in detail.
ß Ask me about the latest results on quasars at high (z~6)
quasars…
