cds-question@unistra.frquasarsradio-sourcesradio-astronomyWe present a catalogue of the 322 damped Lyman alpha absorbers taken from the literature. All damped Lyman alpha absorbers are included, with no selection on redshift or quasar magnitude. Of these, 123 are candidates and await confirmation using high resolution spectroscopy. For all 322 objects we catalogue the radio properties of the background quasars, when known. Around 60 quasars have radio flux densities above 0.1Jy and approximately half of these have optical magnitudes brighter than V=18. This compilation should prove useful in several areas of extragalactic/cosmological research.2002PASA...19..455Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/PASA/19.455CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/224 : Quasars and Active Galactic Nuclei (10th Ed.)
