Abstract:
We present a study of the environment of the Swift long gamma-ray
burst GRB 120327A at z∼2.8 through optical spectroscopy of its
afterglow.
We analyzed medium-resolution, multi-epoch spectroscopic observations
(R∼7000-12000, corresponding to ∼15-23km/s, S/N=15-30 and wavelength
range 3000-25000Å) of the optical afterglow of GRB 120327A, taken
with X-shooter at the VLT 2.13 and 27.65hr after the GRB trigger.
