Abstract

We select energetic GRBs detected by Fermi-LAT/GBM with known redshift and compute the correlation between the intrinsic peak luminosity (L_iso) and peak energy (E_i,p) of the νF_ν energy spectrum, known as the Yonetoku relation, in the 1 keV–10 MeV and 1 keV–30 MeV energy ranges. This correlation has the potential to make GRBs standard candles, similar to type Ia supernovae, but extending to high redshift. We explore parameters of the Lambda-Cold-Dark-Matter cosmological model at high redshift using Yonetoku relation for our sample of GRBs.
