Very high column density and small reddening toward GRB 020124 at z=3.20
Publication: Research - peer-review › Journal article – Annual report year: 2003
We present optical and near-infrared observations of the dim afterglow of GRB 020124, obtained between 2 and 68 hr after the gamma-ray burst. The burst occurred in a very faint (Rgreater than or similar to29.5) damped Lyalpha absorber (DLA) at a redshift of z=3.198+/-0.004. The derived column density of neutral hydrogen is log(N-Hi)=21.7+/-0.2, and the rest-frame reddening is constrained to be E(B-V)
