Title:Lost and Found: The Damped Lyman Alpha Absorbers in the QSO OI 363

Authors:Judith G. Cohen
View PDF
Abstract: The galaxy giving rise to the damped Ly$\alpha$ absorbing system in the QSO OI 363 with z=0.221 has been found. A galaxy which is probably associated with the second DLA in this same QSO at z=0.0912 has also been found. Neither galaxy is very luminous, and neither galaxy shows signs of extensive current star formation, a massive disk or lots of gas. The impact parameters for each of the two galaxies with respect to the QSO are reasonable. If most DLA absorbers arise in such low luminosity galaxies, it will be difficult to pick out the correct galaxy giving rise to DLA systems at high redshift within the large projected areal density on the sky of faint galaxies around distant QSOs.
