Beschreibungen/Notizen

• We report preliminary results of the observation of the GRB 021004 host galaxy and field obtained with the new VLT/X‐shooter spectrograph. Thanks to the X‐shooter wide spectral range we could detect many emission lines associated to the GRB host at z = 2.33102. Moreover we identify [O III] λλ 4959, 5007 Äemission lines at z = 2.33184 associated with a close‐by galaxy possibly interacting with the GRB host. We do not detect any counterpart of the foreground absorbers found in the afterglow spectra of GRB 021004 (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
