Exploring the most energetic persistent objects in the universe, Beckmann (U. Paris-Diderot) and Shrader (NASA Goddard Space Flight Center) discuss the observational picture of active galactic nuclei; radiative processes; the central engine; types and unification; nuclei through the electromagnetic spectrum; variability; environment; quasars and cosmology; formation, evolution and ultimate fate; and what is not yet known.

作者簡介
Volker Beckmann received his Ph.D. from the University of Hamburg, Germany, for studies of different classes of Active Galactic Nuclei (AGN). He has been working in the field of hard X-ray astronomy in Italy, Switzerland,
and in the US at NASA and taught at the University of Maryland, Baltimore County. As an expert on AGN, he has also worked on hard X-ray missions like INTEGRAL and Swift. Since 2009 he has been responsible scientist for a new data and computing centre for astrophysics in Paris.
Chris R. Shrader is an astrophysicist at the NASA Goddard Space Flight Center in Greenbelt Maryland and is also affiliated with the Universities Space Research
Association. He has been involved with optical, ultraviolet, X-ray and gamma-ray studies of Active Galactic Nuclei as well as accretion-powered Galactic
objects for over 25 years. He currently manages the Fermi Gamma-Ray Space Telescope Science Support Center.
