Study The Mechanism Of The Prompt Emission Of Gamma-Ray Bursts, Wei Deng

UNLV Theses, Dissertations, Professional Papers, and Capstones

The prompt emission of Gamma-Ray Bursts (GRBs) has been detected over 40 years, but the mechanism of the prompt emission is still a mystery. The problem can be summarized as several debatable questions: What is the energy composition of the jets/outflows? What is the energy dissipation mechanism? How are the particles accelerated during the energy dissipation process? What is the radiation mechanism to produce the observed prompt emission? In order to solve these problems, several theoretical models have been proposed, including the classical "internal shock (IS)" model, the "dissipative photosphere" model, the "magnetic dissipation" model, and so on. Different models …
