Overview

Investigation reveals intrinsic GRB properties in a simulated population, indicating significant implications for astrophysics.

Key Points

  • The main aim is to uncover the intrinsic distributions of gamma-ray bursts and their physical origins.
  • Used Monte Carlo-based population modeling to generate large GRB populations.
  • Simulated Fermi-GBM detector response for these populations.
  • Performed spectral fitting on the detected simulated bursts.
  • Compared simulation outputs with actual Fermi-GBM data.
  • Observed properties from simulations align well with actual observations from Fermi-GBM.
  • Notable deviations in the β parameter between intrinsic and observed distributions were identified.
  • Derived intrinsic distributions for luminosity, isotropic energy, and redshift.
  • Estimated a local GRB rate of 1.41 ± 0.22 Gpc −3 yr −1.
