Description
The Sunyaev-Zel'dovich (SZ) effect offers an opportunity to
probe the properties of the intracluster plasma in galaxy
clusters through its interaction with the cosmic microwave
background radiation. I will present the detection of the SZ
effect at 870 micrometers in the Bullet Cluster of Galaxies,
at redshift 0.3. I will discuss the techniques used to
remove background submillimeter galaxies and the filtering
applied to extract the extended SZ emission. By modeling the
data the distribution and properties of the hot gas in the
cluster can be constrained.
