Gamma–Ray Bursts (GRBs) are potentially a very powerful tool for the measure of cosmological parameters. Indeed, they are the brightest sources in the universe (up to more than 1054 erg/s released in a few tens of s), their redshift distribution extends from about 0.1 to at least 6.7, and they radiate mostly in the hard X–ray band, thus avoiding, e.g. , the dust extinction problems affecting type Ia SNe. However, the luminosities of GRBs span several orders of magnitude, thus a way to…
