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…
Galactic nebular lines in the fiber spectra of background QSOs: Reaching a hundred QSO-galaxy pairs with spectroscopic and photometric measurements
Lorrie Straka, Pasquier Noterdaeme, Raghunathan Srianand +6
We present photometric and spectroscopic measurements of 53 QSO-galaxy pairs from the Sloan Digital Sky Survey, where nebular emission lines from a 0<z<0.84 foreground galaxy are d…
The dust, nebular emission and dependence on QSO radio properties of the associated Mg II absorption line systems
Pushpa Khare, Daniel Vanden Berk, Hadi Rahmani +1
We studied dust reddening and [O II] emission in 1730 Mg II associated absorption systems (AAS; relative velocity with respect to QSOs, < 3000 km/s; in units of velocity of light,…
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…
Galaxies with Background QSOs, I: A Search for Strong Galactic H-alpha Lines
Donald G. York, Lorrie A. Straka, Michael Bishof +12
A search for emission lines in foreground galaxies in quasar spectra (z(gal) < z(QSO)) of the Sloan Digital Sky Survey (SDSS) data release 5 (DR5) reveals 23 examples of quasars sh…
