Abstract
Gotz et al. GCNC 32660 - Eiso = 8e53 ergs in [75 keV 1 MeV] ; Frederiks et al. GCNC 32668 - Eiso = 3e54 ergs in [20 keV - 10 MeV ?] ; Kann et al. GCNC 32762 - Eiso = 6e54 ergs in [0.1 keV - 100 MeV] ; We discuss here the chance to observe such an energetic GRB at redshift z = 0.151 (de Ugarte Postigo GCNC 32648, Castro-Tirado et al. GCNC 32686), considering the rate of such extremely energetic GRBs observed at higher redshifts. Considering a flat cosmology with H0 = 67.4 km/s/Mpc and Omegam = 0.315 (Planck Collaboration et al. 2020), we extrapolate the rate of ≈4 extremely energetic GRBs per year derived by Atteia et al. (2017) in the redshift range [1,5], to the volume of the nearby universe enclosed within z = 0.151. - Assuming a constant GRB formation rate, we obtain 1 extremely energetic GRB per ~130 yr. - Assuming the GRB formation rate of Palmerio & Daigne (2021), we obtain 1 extremely energetic GRB per ~520 yr. We conclude that there is a ~10% probability to observe an event like GRB 221009A about 50 years after the discovery of the first GRB. Bibliography : - Cenko, S. B., Frail, D. A., Harrison, F.
