Lost and found: the damped Lyα absorbers in the QSO OI 363.

COHEN J.G.

Abstract (from CDS):

The galaxy giving rise to the damped Lyα absorbing system with z=0.221 in the QSO OI 363 has been found. A galaxy that is probably associated with the second damped Lyα absorber (DLA) in the same QSO (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 both galaxies with respect to the QSO are reasonable. If most DLAs arise in such low-luminosity galaxies, it will be difficult to pick out the correct source galaxy for DLA systems at high redshift, given the large projected areal density on the sky of faint galaxies around distant QSOs.
