NED Abstract

Copyright by Royal Astronomical Society. 2000MNRAS.316L..24H A measurement at the first acoustic peak of the cosmic microwave background with the 33-GHz interferometer D. L. Harrison, J. A. Rubino-Martin, S. J. Melhuish, R. A. Watson, R. D. Davies, R. Rebolo, R. J. Davis, C. M. Gutierrez and J. F. Macias-Perez Accepted 2000 June 7. Received 2000 May 22; in original form 2000 March 24 ABSTRACT This paper presents the results from the Jodrell Bank-Instituto de Astrofisica de Canarias (IAC) two-element 33-GHz interferometer operated with an element separation of 32.9 wavelengths and hence sensitive to 1^deg^-scale structure on the sky. The level of cosmic microwave background (CMB) fluctuations, assuming a flat CMB spatial power spectrum over the range of multipoles l = 208+/-18, was found using a likelihood analysis to be {DELTA}T_l_ = 63_-6_^=7^ microK at the 68 per cent confidence level, after the subtraction of the contribution of monitored point sources. Other possible foreground contributions have been assessed and are expected to have negligible impact on this result. Keywords: instrumentation: interferometers - cosmic microwave background- cosmology: observations - large-scale structure of Universe
