... In one situation, we can use light from quasars to probe the material between us and them because that light may pass through one or more galaxies or gas clouds on its way to us. The gas inside the galaxies or the intergalactic clouds acts then as a filter, absorbing selected wavelengths from the quasar light. ... Light from a quasar must pass through clouds of gas and even faint galaxies -- each leaving its imprint on the light -- before we receive it here on Earth. ... Gravitational lensing . ...

We present the results of a mini-survey for associated H I 21-cm absorption at z 0.42 with the Giant Metrewave Radio Telescope. Our targets are radio galaxies, selected on the basis that the 1216 luminosities are below L UV 10 23 W Hz -1 , above which there has never been a detection of 21-cm absorption. ... In the case of the detection, the absorption only occurs towards one of the two resolved radio lobes in PKS 1649-062. ...
