The prompt spectra of gamma-ray bursts are known to follow broadband continuum behavior over decades in energy. GRB 221009A, given the moniker the brightest of all time (BOAT), is the brightest gamma-ray burst identified in half a century of observat

Exploring Physically-Motivated Models to Fit Gamma-Ray Burst Spectra

Autor: Poolakkil, Suraj, Preece, Robert, Veres, Peter

We explore fitting gamma-ray burst spectra with three physically-motivated models, and thus revisit the viability of synchrotron radiation as the primary source of GRB prompt emission. We pick a sample of 100 bright GRBs observed by the Fermi Gamma-r

Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about particle acceleration in environments so extreme they cannot be reproduce

The Spectral Sharpness Angle of Gamma-ray Bursts

Autor: Yu, Hoi-Fung, van Eerten, Hendrik J., Greiner, Jochen, Sari, Re'em, Bhat, P. Narayana, von Kienlin, Andreas, Paciesas, William S., Preece, Robert D.

We explain the results of Yu et al. (2015b) of the novel sharpness angle measurement to a large number of spectra obtained from the Fermi gamma-ray burst monitor. The sharpness angle is compared to the values obtained from various representative emis

Which $E_{\rm peak}$? - The Characteristic Energy of Gamma-Ray Burst Spectra

Autor: Preece, Robert, Goldstein, Adam, Bhat, Narayana, Stanbro, Matthew, Hakkila, Jon, Blalock, Dylan

Publikováno v: ApJ, 821, 12 (2016)

A characteristic energy of individual gamma-ray burst (GRB) spectra can in most cases be determined from the peak energy of the energy density spectra ($\nu{\cal F}_{\nu}$), called '$E_{\rm peak}$'. Distributions of $E_{\rm peak}$ have been compiled
