Cosmic Background Radiation Temperature Anisotropy: Position of First Doppler Peak
Abstract
The purpose of the Cosmic Background Radiation (CBR) experiments is to measure the temperature anisotropy via the autocorrelation function. The partial wave l1 corresponding to the first Doppler peak caused by baryon-photon oscillations at the surface of last scattering depends on the present density 0 and the cosmological constant contribution . We discuss this dependence on the basis of perspicuous figures.
