Metal abundances at z<1.5: new measurements in sub-Damped Lyman-alpha Absorbers

C. Peroux, J. D. Meiring, V. P. Kulkarni +4

Damped Lyman-alpha systems (DLAs) and sub-DLAs seen toward background quasars provide the most detailed probes of elemental abundances. Somewhat paradoxically these measurements ar…

Narrow associated QSO absorbers: clustering, outflows and the line-of-sight proximity effect

Vivienne Wild, Guinevere Kauffmann, Simon White +8

Using data from the Sloan Digital Sky Survey data release 3 (SDSS DR3) we investigate how narrow (<700km/s) CIV and MgII quasar absorption line systems are distributed around quasa…

Average Properties of a Large Sample of z_abs ~ z_em associated Mg II Absorption Line Systems

D. Vanden Berk, P. Khare, D. G. York +16

We have studied a sample of 415 associated (z_ab z_em; relative velocity with respect to QSO <3000km/s) Mg II absorption systems with 1.0<=z_ab<=1.86, in the spectra of SDSS DR3 QS…

The chemical compositions of 10 new sub-DLAs and strong Lyman-limit systems at z < 1.5

Joseph D. Meiring, Varsha P. Kulkarni, James T. Lauroesch +4

We present chemical abundance measurements from medium resolution observations of 8 sub-damped Lyman-alpha absorber and 2 strong Lyman-limit systems at z < 1.5 observed with the MI…

New abundance determinations in z < 1.5 QSO absorbers: seven sub-DLAs and one DLA

Joseph D. Meiring, James T. Lauroesch, Varsha P. Kulkarni +4

We present chemical abundance measurements from high resolution observations of 7 sub-damped Lyman-alpha absorbers and 1 damped Lyman-alpha system at z<1.5. Three of these objects…

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…
