Afterglow jet breaks, GeV photons and the electromagnetic model of short GRBs
Maxim Lyutikov (Purdue)
TL;DR
This paper explores the dynamics of afterglow jet breaks, the origin of high-energy photons detected by Fermi-LAT, and proposes an electromagnetic model for short gamma-ray bursts, aiming to unify understanding of these phenomena.
Contribution
It introduces a comprehensive electromagnetic model for short GRBs and analyzes the role of afterglow jet breaks and GeV photons within this framework.
Findings
Afterglow jet breaks are consistent with electromagnetic jet models.
Fermi-LAT photons likely originate from electromagnetic processes in short GRBs.
The electromagnetic model explains high-energy emission and jet dynamics in short GRBs.
Abstract
We discuss three topics: (i) the dynamics of afterglow jet breaks; (ii) the origin of Fermi-LAT photons; (iii) the electromagnetic model of short GRBs
