Solving the conundrum of intervening strong MgII absorbers towards GRBs and quasars
L. Christensen, S. D. Vergani, S. Schulze +33
Previous studies have shown that the incidence rate of intervening strong MgII absorbers towards GRBs were a factor of 2 - 4 higher than towards quasars. Exploring the similar size…
The comoving mass density of MgII from to
Alex Codoreanu, Emma V. Ryan-Weber, Neil H. M. Crighton +4
We present the results of a survey for intervening MgII absorbers in the redshift range z 2-6 in the foreground of four high redshift quasar spectra, 5.796.1…
A deep search for metals near redshift 7: the line-of-sight towards ULAS J1120+0641
Sarah E. I. Bosman, George D. Becker, Martin G. Haehnelt +5
We present a search for metal absorption line systems at the highest redshifts to date using a deep (30h) VLT/X-Shooter spectrum of the z = 7.084 quasi-stellar object (QSO) ULAS J1…
