The last few years have seen tremendous growth in our understanding of the
physics of galaxy clusters and their relation to cosmology. One of the latest
and most interesting tools in this analysis has been the availability of
large-area imaging of galaxy clusters using the Sunyaev-Zel'dovih Effect (SZE),
with the help of state-of-the-art multi-pixel bolometer arrays. Several such
experiments with new generation of bolometer receivers are now collecting
data and producing their first results. The APEX-SZ instrument, commissioned
in Spring 2007, is one of the first such experiments and is in the process of
announcing its first scientific results.
One particular strength of such large-area SZE maps is to use them in
combination with X-ray and weak-lensing data to extend our understanding of
the physical and dynamical properties of the intra-cluster gas (ICM) out to a
large fraction of the cluster virial radius. The aim of the workshop will be
to bring together experts of such multi-wavelength ICM analysis and discuss
the recent results from new SZE experiments as well as their combination with
other observational probes.
Since APEX-SZ is unique in its sensitivity, resolution and ability to track
sources, resulting in detailed SZE maps of known galaxy clusters, it is our
aim to put current and future APEX-SZ time to its best possible use by
developing a joint plan for observation and target selection with a
broader community.
As mentioned above, we aim to focus on cluster physics rather than surveys, so
the topics will include: cluster ICM modeling combining SZ, X-ray,
and possibly weak lensing data; cluster SZE scaling relations; cosmology
from cluster baryon fractions; etc. We aim to make possible for every
participant to present their latest works.
