[55.01] CMB Anisotropy Measurements with the Degree Angular Scale Interferometer (DASI)

J. E. Carlstrom (University of Chicago), DASI Collaboration

The Degree Angular Scale Interferometer (DASI) is a 13-element array of horns operating at 26 - 36 GHz designed explicitly to image anisotropy in the Cosmic Microwave Background radiation and to determine its angular power spectrum over the range 140 < l < 920. DASI was deployed sucessfully at the Amudsen-Scott South Pole station last Austral Summer (December 1999 - January 2000) and has collected high quality data throughout the Austral Winter. After a brief overview of the instrument and its capabilities, the talk will focus on the observations and on the results of the data analysis.

DASI is funded by NSF-OPP via the Center for Astrophysical Research in Antarctica, a NSF STC.
