New Frontiers in AGN Astrophysics: The X-ray Perspective

Abstract

After four years of dedicated service from the new generation of X-ray telescopes, XMM-Newton and Chandra, as well as results obtained from various multiwavelength observations, we are at a good point to revisit the topic of AGN physics. This proceeding will review the basic open questions posed by earlier X-ray missions which have now been answered, as well as address new questions which still require further investigation. The topics critically discussed will include: the physics of the innermost region of AGN, the nature of sharp spectral drops in the high-energy spectra of NLS1s, as well as new aspects of Seyfert unification.
