Detecting cold gas at intermediate redshifts: GMRT survey using Mg II systems
Neeraj Gupta, R. Srianand, P. Petitjean +3
Intervening HI 21-cm absorption systems at z > 1.0 are very rare and only 4 confirmed detections have been reported in the literature. Despite their scarcity, they provide interest…
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…
Extinction and metal column density of HI regions up to redshift z~2
G. Vladilo, M. Centurion, S. A. Levshakov +4
We used the photometric database of the Sloan Digital Sky Survey (SDSS) to estimate the reddening of 13 SDSS quasars selected on the basis of the presence of zinc absorption lines…
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…
