Scientific paper

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 Å emission 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.
Based on observations made with ESO Telescopes at the Paranal Observatories under programme ID 084.A-0631, PI: S. Piranomonte.
