Abstract

We will present maps of low redshift Abell clusters made with two instruments, Corona (40 GHz) and ACBAR (150, 210, 275 GHz), that have operated on the Viper telescope at the South Pole. We will describe an attempt to measure Hubble's Constant from a Corona map of A3667 and discuss how this measurement has been hampered by contamination from primary CMB anisotropies. The availability of multi-frequency data from ACBAR has allowed us to subtract the CMB signal and to produce resolved Sunyaev-Zeldovich (SZ) images of A3667 and A3226. We will compare the SZ images of these clusters to weak lensing data and to X-ray data from the ROSAT, ASCA, Chandra and XMM satellites. This work has been supported in part by a NASA LTSA grant; NAG5-7926.
