Workshop on X-ray spectroscopy of active galactic nuclei
with Chandra and XMM-Newton
held at MPE Garching, December 3-6, 2001
Workshop Photos (only on request)
X-ray observations of active galaxies and quasars currently provide the
most powerful way to explore the immediate environments of supermassive
black holes. Our ability to probe these environments underwent a revolution
with the launches of Chandra and XMM-Newton.
The high throughput and excellent spectral cababilities of the new generation
of X-ray observatories allow more precise investigations at the forefront
of active-galaxy/quasar X-ray research and have already revealed many new
and unexpected observational results.
However, some of these are discussed
controversially and require better understanding; e.g.
the nature of the soft X-ray excess, the presence of warm absorber
edges, the location and dynamics of the warm absorber, and spectral features
from the inner accretion disk.
The aim of this workshop is to provide a platform for intense discussion
of these topics.
The nature of the soft X-ray excess
New spectral features and their interpretations; e.g. unresolved
Spectral signatures of the warm absorber
Warm absorber dynamics: Bulk velocity, velocity dispersion, multiple
The relationship between X-ray and ultraviolet absorption
X-ray spectral features from the torus and circumnuclear environment
Grating spectroscopy of the broad and narrow emission lines
New scientific results from the latest observations
Relativistic disk lines at cosmological redshifts
Theoretical interpretations and modeling issues
Future X-ray Fe line reverberation studies
