 Gamma-ray burst emission mechanisms

Gamma-ray bursts (GRBs) are among the most energetic events in the universe, producing intense bursts of gamma-ray radiation. The mechanisms behind their emission can generally be divided into two main categories: **prompt emission** and **afterglow emission**. Here’s an overview of each category along with the primary models associated with them. ### 1. Prompt Emission The prompt emission is the initial burst of gamma-rays that occurs over a time scale of seconds to minutes.
