Simulation of the neutron star coalescence GW190425

Images of GW190425

The images show a numerical simulation representing the binary neutron star coalescence and merger which resulted in the detected gravitational-wave event GW190425. The two non-spinning neutron stars shown in the animations have 1.72 and 1.63 solar masses and follow the ALF2 equation of state (EOS). The employed parameters (total mass, mass ratio, spin and EOSs) are consistent with the detection made on the 25th of April 2019 by the Advanced LIGO/Virgo detectors.
