A Survey of Weak Mgii Absorbers at 0.4 < z < 2.4 1
We present results from a survey of weak Mg ii absorbers in the VLT/UVES spectra of 81 QSOs obtained from the ESO archive. In this survey, we identified 112 weak Mg ii systems within the redshift interval 0.4 < z < 2.4 with 86 % completeness down to a rest-frame equivalent width of Wr(2796) = 0.02 Å, covering a cumulative redshift path length of ∆Z ∼ 77.3. From this sample, we estimate that the...
متن کاملA search for HI 21cm absorption in strong MgII absorbers in the redshift desert
We report results from a deep search for redshifted HI 21cm absorption in 55 strong MgIIλ2796 absorbers (having Wλ2796 0 > 0.5Å) at intermediate redshifts, 0.58 < zabs < 1.70, with the Green Bank Telescope (GBT) and the Giant Metrewave Radio Telescope (GMRT). Nine detections of HI 21cm absorption were obtained, all at 1.17 < zabs < 1.68, including three systems reported earlier by Gupta et al. ...
متن کاملA survey of weak Mgii absorbers at redshift 〈z 〉 = 1.78 1
The exact nature of weak Mg ii absorbers (those with Wr(2796) < 0.3 Å) is a matter of debate, but most are likely related to areas of local star formation or supernovae activity outside of giant galaxies. Using 18 QSO spectra obtained with the Ultra-Violet Echelle Spectrograph (UVES) on the Very Large Telescope (VLT), we have conducted a survey for weak Mg ii absorbers at 1.4 < z < 2.4. We sear...
متن کاملDusty MgII Absorbers: Implications for the GRB/Quasar Incidence Discrepancy
There is nearly a factor of four difference in the number density of intervening MgII absorbers as determined from gamma-ray burst (GRB) and quasar lines of sight. We use a Monte-Carlo simulation to test if a dust extinction bias can account for this discrepancy. We apply an empirically determined relationship between dust column density and MgII rest equivalent width to simulated quasar sight-...
متن کاملSTRONG MgII SYSTEMS IN QUASAR AND GAMMA-RAY BURST SPECTRA
The incidence of strong MgII systems in gamma-ray burst (GRB) spectra is a few times higher than in quasar (QSO) spectra. We investigate several possible explanations for this effect, including: dust obscuration bias, clustering of the absorbers, different beam sizes of the sources, multiband magnification bias of GRBs, association of the absorbers with the GRB event or the circumburst environm...
