Hubble Space Telescope Observations of Sub-Damped Lyman-alpha Absorbers at z < 0.5, and Implications for Galaxy Chemical Evolution

Debopam Som, Varsha P. Kulkarni, Joseph Meiring +5

We report observations of four sub-damped Lyman-alpha (sub-DLA) quasar absorbers at z<0.5 obtained with the Hubble Space Telescope Cosmic Origins Spectrograph. We measure the avail…

Galaxies with Background QSOs: II. An Automated Search for Multiple Galaxy Emission Lines

Lorrie Straka, Zakary L. Whichard, Varsha P. Kulkarni +4

We have improved upon our previous search technique of systematically searching QSO spectra for narrow galactic H-alpha emission, which indicates a foreground galaxy within the Slo…

Element Abundances at High-redshift: Magellan MIKE Observations of sub-Damped Lyman-alpha Absorbers at 1.7 < z <2.4

Debopam Som, Varsha P. Kulkarni, Joseph Meiring +4

We present chemical abundance measurements from high-resolution observations of 5 sub-damped Lyman-alpha absorbers at 1.7 < z < 2.4 observed with the Magellan Inamori Kyocera Echel…

A Super-Damped Lyman-alpha QSO Absorber at z=2.2

Varsha P. Kulkarni, Joseph Meiring, Debopam Som +4

We report the discovery of a "super-damped" Lyman-alpha absorber at toward QSO Q1135-0010 in the Sloan Digital Sky Survey, and follow-up VLT UVES spectroscopy. Voi…

Exploring the dust content of SDSS DR7 damped Lyman alpha systems at 2.155.2

Pushpa Khare, Daniel Vanden Berk, Donald G. York +2

We have studied a sample of 1084 intervening absorption systems with 2.155.2, having log(N) 20.0 in the spectra of QSOs in Sloan Digital Sky Survey (S…

SOAR Imaging of sub-Damped Lyman-Alpha Systems at z<1

Joseph D. Meiring, James T. Lauroesch, Lutz Haberzettl +4

We present deep ground based imaging of the environments of five QSOs that contain sub-Damped Lyman-alpha systems at z<1 with the SOAR telescope and SOI camera. We detect a clear s…
