"Probing the High-Redshift Universe with Millimeter-Wave Surveys for Galaxies and Clusters"

Abstract:

Observations with COBE yielded an unresolved, cosmic far-infrared background radiation with integrated power nearly equal to the observed optical and ultraviolet starlight in the Universe. Recent submillimeter and millimeter-wave surveys have begun to resolve this background into galaxies, which appear to lie at z > 1 and have star formation rates exceeding 100 solar masses per year. Characterizing these galaxies is clearly important for a complete picture of galaxy formation. I will describe Bolocam, a new millimeter-wave bolometer camera, our survey for high-redshift galaxies, and the Z-Spec millimeter-wave spectrometer we are building to measure their redshifts. I will also describe our survey for galaxy clusters using the Sunyaev-Zel'dovich effect, which could lead to new measurements of the dark matter and dark energy content of the Universe.
