22 January 2009Speaker: Jane Turner (University of Maryland) Title:X-ray Absorption and Reflection in Active Galactic Nuclei Abstract:X-ray spectroscopy offers an opportunity to study the complex reprocessing regions close to super-massive black holes in active galactic nuclei. X-ray observations can help us learn about the accretion process that fuels these systems and the feedback of material to their host galaxies. I describe the spectral signatures that may be studied in the X-ray band and review what can be learned from X-ray spectral variability of active galaxies, concentrating on progress from recent Chandra, XMM-Newton and Suzaku data.
