Session 7 - Cosmology and Cosmological Parameters.
Display session, Monday, January 15
North Banquet Hall, Convention Center
We report a measurement of the angular power spectrum of the anisotropy in the Cosmic Microwave Background. The anisotropy is measured in 23 different spatial bands (from \ell_o=54 to \ell_o=408) and in 6 frequency bands (from 26\,GHz to 46\,GHz) over three observing seasons. The frequency spectral index of the fluctuations is consistent with that of the CMB, and inconsistent with either Galactic free-free emission or dust. The measurements are consistent from year to year. Furthermore, the sky coverage of the MSAM experiment (Cheng et al. 1994) was repeated and the results confirmed. The angular power spectrum shows a distinct rise from \delta T_\ell = 49.2^+7.5_-5.0\,\muK at \ell = 83 to 80.4^+9.5_-8.1\,\muK at \ell = 234.
