The gravitational wave (GW) detected in 2015 is a milestone in science, that proves the most important prediction of Einstein’s general relativity and GW also opens a new window of the astronomical observation. Therefore, numerical relativity is getting more attention since it can provide a powerful tool to study the physics of GW sources. Among all promising sources of GW, neutron star merger is the richest exploitation in general relativity. We used Einsteintoolkit to perform a series of merger simulations with different mass ratios of two neutron stars in different environments. In this talk, I will talk about the results of my relativistic calculations of binary neutron star mergers, that may explain the observed GW sources and provide a better understanding of their underlying physics.
