Description

From a survey for the redshifted Hi 21-cm and OH 18-cm absorption in the hosts of a sample of radio galaxies and quasars, we detect Hi in three of the 10 and OH in none of the 14 sources for which useful data were obtained. As expected from our recent result, all of the 21-cm detections occur in sources with ultraviolet (UV) continuum luminosities of LUV≤ 1023WHz-1. At these 'moderate' luminosities, we also obtain four non-detections, although, as confirmed by the equipartition of detections...[Show more]
