High-redshift quasars and blazars and their relation to high-redshift galaxies

High-redshift quasars and blazars are among the most powerful sources in the Universe and among the highest luminosity sources, as in optical, so as in X-ray, UV, IR and radio range. We have created a full sample of blazars and high-redshift quasars (z>=2.15). The evolutionary relation of high-redshift quasars and blazars to high-redshift galaxies is discussed using the luminosity evolution.
