Neutron Star Merger Simulation with Gamma-ray Observations

Published: February 2, 2023

This animation follows the gravitational wave and density changes in a simulated neutron star merger and compares them to measurements of a short gamma-ray burst observed by NASA's Compton mission on July 11, 1991.
