General Relativistic Simulations of High-Mass Binary Neutron Star Mergers: rapid formation of low-mass stellar black holes

Understand

Almost a hundred compact binary mergers have been detected via gravitational waves by the LIGO-Virgo-KAGRA collaboration in the past few years providing us with a significant amount of new information on black holes and neutron stars.

• In addition to observations, numerical simulations using newly developed modern codes in the field of gravitational wave physics will guide us to understand the nature of single and binary degenerate systems and highly energetic astrophysical processes.
• We here presented a set of new fully general relativistic hydrodynamic simulations of high-mass binary neutron star systems using the open-source Einstein Toolkit and LORENE codes.
• We considered systems with total baryonic masses ranging from 2.8 $M_\odot$ to 4.0 $M_\odot$ and used the SLy equation of state.
