The Parkes Lens Survey

Abstract

We are undertaking an extensive survey of a sample of radio-selected flat-spectrum sources, which are predominantly quasars. The sample will be used for a range of gravitational lensing studies as well as studies of the generic properties of radio quasars. As yet we have not found any instances of multiply-imaged quasars, however we have found evidence for dust which we believe is reddening the observed spectra of many of the quasars. Samples which are selected to be complete in the radio are the best way to account for the effects of dust.
