Abstract

We will present Sunyaev-Zel'dovich observations of eight Southern clusters of galaxies selected from the REFLEX catalog. The observations were made at 150, 220 and 275 GHz using the Arcminute Cosmology Bolometer Array Receiver (ACBAR) installed on the 2m Viper Telescope at the South Pole. The multi-frequency data permit the subtraction of the signal from primary CMB anisotropies from cluster images. The clusters range in redshift from z=0.05 to z=0.35 and form a luminosity limited sample. We will compare the ACBAR raster scan images of these clusters to weak lensing maps and to X-ray data from the ROSAT, Chandra and XMM satellites. This work has been supported in part by a NASA LTSA grant; NAG5-7926
