The physics of galactic nuclei has recently attracted substantial renewed
interest, also due to the tentative connection to galaxy evolution.
Spectacular new high spatial resolution observations based on adaptive optics
(SINFONI, NACO) and interferometric techniques (MIDI) recently unveiled
unexpected new details of the central region of our own galactic centre, as well
as nearby Seyfert galaxies. A consistent model has been developed that can
explain different types of active galactic nuclei (AGN) as a result of inclination
angle dependence of a torus surrounding an accretion disk around a central black hole.
Current research focuses on the interaction with the intense
radiation field,
interaction of gas streams pointing towards the centre or star
formation and
subsequent feedback from a nuclear stellar cluster. These processes
might stir
turbulence in the Broad Line Region (BLR), the adjacent molecular/
dusty torus
or the Narrow Line Region (NLR). The resulting multiphase turbulence
governs the
small-scale dynamical as well as thermodynamical evolution of the gas
and
necessitates special numerical techniques. This, together with the
development
of new efficient codes concerning the coupling of radiative transfer
with
hydrodynamics enables a realistic treatment of the main physical
processes
acting in the complicated environment we are facing in galactic
nuclei.
The link to the large scale structure of the galaxy is given by black
hole feedback,
constrained for example by the black hole sigma relation and the
redshift
evolution of AGN. A better understanding of the physics of the
galactic centre
environment and its possible physical feedback processes towards
larger scales,
is therefore also essential for quantitative modelling of galaxy
evolution.
The main aim of this workshop is to bring together observers and
theoreticians
working in the fields of active as well as currently inactive
galactic nuclei and the
connection of AGN to galaxy evolution, in order to acquire a more
complete picture
and to foster new collaborations.
