AbstractWe show that the empirical E-p-L, Gamma-L, E-p-Gamma, and (eta) over bar (gamma)-E-p correlations (where L is the time-averaged luminosity of the prompt emission, E-p is the spectral peak energy, Gamma is the bulk Lorentz factor, and (eta) over bar (gamma) is the emission efficiency of gamma-ray bursts, GRBs) are well consistent with the relations between the analogous parameters predicted in the photospheric radiation model of the prompt emission of GRBs. The time-resolved thermal radiation of GRB 090902B does follow the E-p-L and Gamma-L correlations. A reliable interpretation of the four correlations in alternative models is still lacking. These may point toward a photospheric origin of prompt emission of some GRBs.
