Overview
Long gamma-ray bursts are among the most powerful explosions in the universe, providing critical insights into the life cycles of massive stars and the dynamics of cosmic evolution. They occur when massive stars collapse into black holes, resulting in intense emissions of gamma radiation that can be...
