Synchrotron radiation in $\gamma$-ray burst prompt emission

Abstract

Growing evidence suggests that synchrotron radiation plays a significant role in shaping the spectra of most $\gamma$-ray bursts. The relativistic jets producing them likely carry a significant fraction of energy in the form of a Poynting flux.
