Description
The Atacama Cosmology Telescope (ACT) has mapped the microwave sky to
arcminute scales. We will present the spectrum at 148 and 218 GHz from
the 2008 season of the Southern Survey of the Atacama Cosmology
Telescope. Improved map-making and efficient spectrum estimation allow
us to recover the second through seventh acoustic peaks, and provide
independent confirmation of the LCDM paradigm. After discussing the
telescope and tests of the spectra, we will describe constraints on
both primary cosmological parameters and secondary parameters from the
small-scale power spectrum, including diffuse SZ emission and
foregrounds.
