The four gravitational wave observatories around the world have been busy lately, revealing hundreds of detections. These ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

The final dance of a black hole and a neutron star before their ultimate merger has been revealed, according to new research.

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

The transformation of neutrinos in a neutron star merger could be crucial to shaping the way events of the collision unfold. For the first time, a team of physicists has simulated how neutrinos change ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Rochester Institute of Technology is advancing computer simulations to predict, for the first time, the complete cycle of neutron stars merging with other neutron stars or black holes. These extreme ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how these systems form.
