Observational Cosmology

Radio surveys play an important role in observational cosmology. However, until recently the surveys have been either of wide area but with low sensitivity or of small area with high sensitivity. Both limit the kinds of cosmology that can be carried out with radio surveys. This situation has been revolutionized recently by the availability of new, large-area, high-sensitivity radio surveys at both high and low frequencies. Significant improvements have now been made which allow studies based on both the statistics of the surveys themselves and multi-wavelength follow-up of the galaxies and AGN responsible for the radio emission. This book comprises the proceedings of the "Observational Cosmology with the New Radio Surveys" workshop, held on Tenerife, January 13-15, 1997. Topics covered include: lessons learned and important results from earlier surveys, descriptions of some of the new surveys, clusters of galaxies and large-scale structure, radio source evolution, CMB studies, gravitational lensing and multiwavelength studies of distant radio sources.
