A log N(HI) = 22.6 DLA in a dark gamma-ray burst: the environment of GRB 050401

D. Watson, J. P. U. Fynbo, C. Ledoux +33

The optical afterglow spectrum of GRB050401 (at z=2.8992+/-0.0004) shows the presence of a DLA, with log(nHI)=22.6+/-0.3. This is the highest column density ever observed in a DLA,…
