Ionization of the atomic gas in redshifted radio sources
We report the results of a survey for H I 21-cm absorption at z ≲ 0.4 in a new sample of radio sources with the Giant Metrewave Radio Telescope. Of the 11 sources for which there are good data, we obtain zero detections, where four are expected upon accounting for the ionizing photon rates and sensi...
