Socialization : 10:15 a.m.
Presentation : 10:30 a.m.

The Sunyaev-Zel'dovich Effect,a long-predicted but only recently detected imprint on the spectrum of the cosmic microwave background, can be used to examine the formation and evolution of the early Universe. We have just completed an 8-element interferometer dedicated to Sunyaev-Zel'dovich Effect measurements -- the SZ Array -- and will describe the construction and scientific capabilities of the array, the survey strategy, and future directions in SZ imaging.

BIOGRAPHICAL SKETCH:
