Supercomputer Simulations Reveal Stunning Details of Neutron Star-Black Hole Collisions
2025-06-19

Scientists used supercomputers to simulate neutron star-black hole collisions, revealing that before the collision, the neutron star is torn apart by the black hole's gravity, generating Alfvén waves and a final burst of radio waves lasting about a second. The collision also produces the universe's strongest shock waves and may form a brief black hole pulsar, emitting high-energy X-rays or gamma rays. This research, leveraging the powerful GPU computing capabilities of the Perlmutter supercomputer, provides crucial clues for detecting these most violent events in the universe.
