The nature of damped Lyman alpha and sub-damped Lyman alpha absorbers
Pushpa Khare, Varsha P. Kulkarni, Celine Peroux +3
We present arguments based on the measured abundances in individual damped Lyman alpha systems (DLAs) and sub-damped Lyman alpha systems (sub-DLAs), and also the average abundances…
The Role of Sub-damped Lyman-alpha Absorbers in the Cosmic Evolution of Metals
V. P. Kulkarni, P. Khare, C. Peroux +3
Observations of low mean metallicity of damped Lyman-alpha (DLA) quasar absorbers at all redshifts studied appear to contradict the predictions for the global mean interstellar met…
Metal-rich Damped/sub-Damped Lyman-alpha Quasar Absorbers at z<1
C. Peroux, J. D. Meiring, V. P. Kulkarni +5
Damped Lyman-alpha absorbers (DLAs), seen in absorption against a background quasar, provide the most detailed probes available of element abundances in the Universe over > 90 % of…
Elemental Abundance Measurements in Low-redshift Damped Lyman Alpha Absorbers
Joseph D. Meiring, Varsha P. Kulkarni, Pushpa Khare +6
We present elemental abundance measurements for 9 damped Ly-alpha systems (DLAs) and 1 sub-DLA at 0.1 < z < 1.5 from recent observations with the Multiple Mirror Telescope. Most of…
Average Extinction Curves and Relative Abundances for QSO Absorption Line Systems at 1 <= z_abs < 2
Donald G. York, Pushpa Khare, Daniel Vanden Berk +21
We have studied a sample of 809 Mg II absorption systems with 1.0 < z_abs < 1.86 in the spectra of SDSS QSOs, with the aim of understanding the nature and abundance of the dust and…
The Most Metal-Rich Intervening Quasar Absorber Known
C. Peroux, V. P. Kulkarni, J. Meiring +5
The metallicity in portions of high-redshift galaxies has been successfully measured thanks to the gas observed in absorption in the spectra of quasars, in the Damped Lyman-alpha s…
