Supercomputer shows black hole cracking neutron star in final explosive seconds

SMRTR summary

A groundbreaking simulation using the Perlmutter supercomputer has revealed how a black hole tears apart a neutron star in its final moments. The simulation shows the neutron star's crust cracking like an earthquake, triggering powerful magnetic waves that could produce detectable radio signals. After the neutron star is consumed, monster shock waves and a short-lived "black hole pulsar" are created. These findings could help astronomers identify black hole-neutron star mergers using electromagnetic signals in addition to gravitational waves.
