Bayesian Time-Resolved Spectroscopy of GRB Pulses

Understand

We performed time-resolved spectroscopy on a sample of 38 single pulses from 37 gamma-ray bursts detected by the Fermi/Gamma-ray Burst Monitor during its first 9 years of mission.

• For the first time a fully Bayesian approach is applied.
• A total of 577 spectra are obtained and their properties studied using two empirical photon models, namely the cutoff power law and Band model.
• We present the obtained parameter distributions, spectral evolution properties, and parameter relations.
