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…
GRB 060121: Implications of a Short/Intermediate Duration Gamma-Ray Burst at High Redshift
A. de Ugarte Postigo, A. J. Castro-Tirado, S. Guziy +23
Since the discovery of the first short-hard gamma-ray burst afterglows in 2005, the handful of observed events have been found to be embedded in nearby (z < 1), bright underlying g…
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…
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…
