• Quasars evolve in<br />
• (i) space density;<br />
• (ii) intrinsic luminosity Æ quasars at higher<br />
redshifts are more luminous.<br />
• Æ High redshift quasars are hosted by<br />
massive galaxies (ellipticals) !<br />
• Æ Large samples of quasars which must<br />
be investigated in UVX-bump, HX-ray,<br />
radio <strong>and</strong> IR properties !<br />
• Æ Cosmological consequences: clustering<br />
as a function of redshift.
