Review of Ground-Based CMB Experiments

Abstract

We present in this paper a brief review of Ground-Based Cosmic Microwave Background (CMB) experiments. We first recall the main experimental problems and adopted solutions. We then review the Tenerife experiments, giving an update together with some new results. Then results and problems from other experiments are highlighted including IAC-Bartol, Python, Saskatoon, Mobile Anisotropy Telecope (MAT) and the Owen Valley Radio Observatory (OVRO) experiments. We next move on to the future ground experiments, in particular new interferometers such as the Very Small Array (VSA), the Cosmic Background Imager (CBI) and the Degree Angular Scale Interferometer (DASI/VCA). To finish, very recent work is presented on joint likelihood analysis for estimation of cosmological parameters where both CMB results and Large Scale Structure (LSS) surveys are considered.
