Description
Clusters of galaxies trace the matter distribution in the universe and
are sensitive probes of growth of structure. A relatively new method to
detect clusters is via their effect on the Cosmic Microwave Background,
known as the SZ-effect. It is currently becoming experimentally feasible
to detect new clusters through large-diameter mm-wavelength telescopes
such as the South Pole Telescope.
I will review the cluster survey currently being conducted with the South
Pole Telescope (SPT) and summarize the potential cosmological constraints.
Further, I will discuss the benefits of observing SZ-selected clusters
in the X-ray band. Finally, I focus on some of the first results from
Chandra X-ray observations of the first cluster sample detected via the
SZ-effect.
