The CORALS survey I: New estimates of the number density and gas content of damped Lyman alpha systems free from dust bias
Astronomy and Astrophysics
(Abridged) We present the first results from the Complete Optical and Radio Absorption Line System (CORALS) survey. We have compiled a homogeneous sample of radio-selected QSOs from the Parkes Catalogue and searched for damped Lyman alpha systems (DLAs) towards every target, irrespective of its optical magnitude. This approach circumvents selection effects -- particularly from intervening dust -- which have long been suspected to affect DLA surveys in optically-selected, magnitude-limited QSOdoi:10.1051/0004-6361:20011281 fatcat:kqxubez6nbcsfbqx6q54lq5ni4
