Discovery of a Low-redshift Damped Lyα System in a Foreground Extended Disk Using a Starburst Galaxy Background Illuminator

Identification of a Galaxy Responsible for a High-Redshift Damped Lyα Absorption System

Hi 21cm Absorption in Two Low Redshift Damped Lyα Systems

We report the discovery of two low redshift HI 21cm absorbers, one at z = 0.2212 towards the z em = 0.630 quasar OI 363 (B0738+313), and the other at z = 0.3127 towards PKS B1127-145 (z em = 1.187). Both were found during a survey of MgII selected systems at redshifts 0.2 < z < 1 using the new UHF-high system at the Westerbork Synthesis Radio Telescope (WSRT). New HST/FOS observations also iden...

On the Relation between High-redshift Starburst Galaxies and Damped Lyα Systems

Essentially all high redshift galaxies show evidence for strong large-scale outflows that should have a profound effect on the structure and kinematics of both the galaxies themselves and their environments. The interstellar absorption spectra of both Lyman break galaxies (LBGs) and local starburst galaxies are remarkably similar to those of damped Lyα (DLA) systems in QSO spectra. Their rest-f...

Discovery of a z = 0.808 damped Lyα system candidate in a UV selected quasar spectrum

We present the observation of a new intermediate redshift damped Lyα absorption system candidate, discovered in the course of a spectroscopic follow-up for identifying the sources detected in a 150Å-wide bandpass UV-imaging survey at 2000 Å. The system displays very strong Mg ii and Fe ii lines and a high Fe ii/Mg ii ratio, which, following photoionization models, indicates a very high neutral ...

The NATURE OF DAMPED Lyα ABSORBING GALAXIES AT z ≤ 1–A PHOTOMETRIC REDSHIFT SURVEY OF DAMPED Lyα ABSORBERS

We study the nature of damped Lyα absorption (DLA) systems at z ≤ 1 using a sample of 11 DLA galaxies, for which accurate redshift measurements are available. Five of the 11 systems are identified in our on-going photometric redshift survey of DLA galaxies, while the remaining six systems are identified by previous groups using either spectroscopic or photometric redshift techniques. Absolute B...
