Multiwavelength Analysis of Galaxy Clusters
Seth Siegel
Caltech
I will describe the joint analysis of X-ray, weak lensing, strong
lensing, and Sunyaev-Zel'dovich (SZ) measurements of the CLASH sample
of 25 massive galaxy clusters. The high-quality multiwavelength data is
able to constrain more realistic parametric models for the distribution
of dark and baryonic matter in the galaxy clusters, avoiding biases in
mass estimates that result from the assumptions of spherical symmetry
and hydrostatic equilibrium. I will present results for a subsample of
the clusters, including constraints on the level of non-thermal pressure
support in the intracluster medium (ICM). I will conclude by introducing
the Multiwavelength Sub/millimeter Inductance Camera (MUSIC), a new
photometric imaging camera for the Caltech Submillimeter Observatory that
is simultaneously sensitive to four bands at 150, 230, 290, and 350 GHz,
and is ideally suited for studies of the ICM through the SZ effect. I
will discuss the characterization and removal of the various sources of
noise inherent to MUSIC's Microwave Kinetic Inductance Detectors (MKIDs)
and their readout electronics.
