The Atacama Cosmology Telescope Project: A Progress Report

Abstract

The Atacama Cosmology Telescope is a project to map the microwave background radiation at arcminute angular resolution and high sensitivity in three frequency bands over substantial sky areas. Cosmological signals driving such an experiment are reviewed, and current progress in hardware construction is summarized. Complementary astronomical observations in other wavebands are also discussed.

15 pages with 4 figures. Based on talks given at the meeting Fundamental Physics with Cosmic Microwave Background Radiation, Irvine, California, March 2006. See also the ACT web site at http://www.physics.princeton.edu/act
