Survey of quasars over large areas.
Abstract
The physical properties of quasars are discussed based on data acquired by means of several techniques including radio selection, slitless spectroscopy, and X-ray selection. Attention is given to the spatial distribution, luminosity function, clustering, and redshift limits of the objects. The extensive surveys of the Virgo Cluster region are emphasized with reference given to the indicators of absorption and gravitational lensing.
