Description
We present the results of a large search for intrinsic H i 21 cm and OH 18 cm absorption in 145 compact radio sources in the redshift range 0.02 < z < 3.8 with the Green Bank Telescope. We redetect H i 21 cm absorption toward six known absorption systems, but detect no new H i or OH absorption in 102 interference-free sources. Seventy-nine sources have not previously been observed for H i 21 cm absorption. We recover a mean optical depth limit of τ 3σ < 0.023 for all the nondetections in the...[Show more]
