Abstract

The nature of the jets and the role of magnetic fields in gamma-ray bursts (GRB) remains unclear 1, 2. In a baryon-dominated jet only weak, tangled fields generated in situ through shocks would be present 3. In an alternative model, jets are threaded with large scale magnetic fields that originate at the central engine and which accelerate and collimate the… (More)
