  X-shooter is a second generation ESO-VLT instrument that had its first light
in October 2009. It is a single object medium-resolution spectrograph whose
main feature is the capability of covering simultaneously in a single
observation the range from 3000 to 24000 Angstrom. This unique capability is
very well suited to investigate the complex spectra of the optical counterparts
of X/gamma ray sources which usually display signatures of different components
in emission and absorption. In July 2012 we observed with X-shooter a small
sample of counterparts of bright IGR sources in order to better determine their
physical properties. We present the first results of these observations.
