Title: High Resolution Spectroscopy of Gamma-Ray Burst Afterglows
Date: Wednesday, November 4th, 2009
Time: 12:00
Venue: Villa Bazzoni

Abstract: The launch of the Swift mission has opened up new windows in the study
of the Gamma-Ray Bursts. The optical follow-up of the early afterglow
is one among the scientific fields that have been
revolutionized. Thanks to the fast broadcast of the GRB coordinates
and to the rapid response mode systems built up in 8-meter class
telescopes, these afterglows can be observed from hours down to a few
minutes after the GRB explosion. The high signal-to noise achievable
allows us to acquire high resolution spectra, which carry a lot of
information both on the GRB environment and the Inter-Stellar Medium
of high redshift galaxies. I will give a short review of what we have
learned through the high resolution spectroscopy of GRB afterglows. I
will focus in particular on the case of GRB080319B, the first
naked-eye GRB observed to date, for which high resolution observations
reach an unprecedented level of the signal-to-noise ratio.
