X-Ray and Gamma-Ray Properties of Active Galaxies: Highlights from Chandra, XMM and Integral
Abstract
The X-ray observatories XMM-Newton and Chandra provided a wealth of exciting new results, and many more are expected to emerge soon from the Gamma-ray mission INTEGRAL. Chandra delivered X-ray images of outstanding detail, reaching subarcsecond spatial resolution for the first time in X-ray astronomy. XMM-Newton with its high sensitivity provided very high quality X-ray spectra, resolved in great detail with the spectrometers aboard XMM and Chandra for the first time. INTEGRAL is dedicated to imaging and spectroscopy in the X-ray and Gamma-ray regime up to 3 MeV with significantly improved sensitivity and resolution as compared to previous Gamma-ray missions. The imaging and spectral observations are greatly improving our understanding of the physical processes in the central region of active galaxies. The increased sensitivity also enables us to peer into the high-redshift universe beyond z=5 in X-rays. I shall provide a review of recent X-ray and gamma-ray highlights on AGN from low to high redshift, and exciting questions still open.
