The Epeak-Eiso relation revisited with Fermi GRBs: Resolving a long-standing debate?

V. Heussaff, J-L. Atteia, Y. Zolnierowski

We used a sample of GRBs detected by Fermi and Swift to reanalyze the correlation discovered by Amati et al. (2002) between Epi, the peak energy of the prompt GRB emission, and Eis…
