Abstract

The unexpected nearby gamma-ray burst (GRB) GRB 170817A associated with the Laser Interferometer Gravitational-Wave Observatory binary neutron star merger event GW170817 presents a challenge to the current understanding of the emission physics of short GRBs. The event's low luminosity but similar peak energy compared to standard short GRBs are difficult to explain with current models, challenging our understanding of the GRB emission process. Emission models invoking synchrotron radiation from electrons accelerated in shocks and photospheric emission are particularly challenging explanations for this burst.
