Atomic and molecular absorption in redshifted radio sources
We report on a survey for associated H I 21-cm and OH 18-cm absorption with the Giant Metrewave Radio Telescope at redshifts z ≈ 0.2–0.4. Although the low-redshift selection ensures that our targets are below the critical ultraviolet luminosity (LUV ∼ 1023 W Hz−1), which is hypothesized to ionize al...
