Description
The correlation between the photon energy at which the nuFnu spectrum in the cosmological rest-frame peaks, Ep,i, and the isotropic-equivalent radiated energy, Eiso, is one of the most investigated observaitonal properties of Gamma-Ray Bursts (GRB). In addition to its relevance for understanding the physics of prompt emission, identifying sub-classes of GRBs, shedding light on jet structure and viewing angle, the Ep,i - Eiso correlation is provide us with an the psosibility of using GRBs for measuring cosmological parameters. I provide an overview of the observaitonal status of the correlation, of the methods most used wordlwide for exploiting it as a cosmological tool and the perspective advancement expected thanks to next generation facilities.
