Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...
Astronomers analyzing the gravitational-wave event known as GW200105 report evidence that a black hole and neutron star ...
GW200105 reveals an eccentric orbit before merger, challenging formation models.
In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects ...
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 ...
Breakthrough discovery provides new clues about how these celestial bodies - that push the known laws of physics to their ...
A long time ago, in two galaxies about 900 million light-years away, two black holes each gobbled up their neutron star companions, triggering gravitational waves that finally hit Earth in January ...
Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers ...
New simulations show that hot neutrinos created at the interface of merging binary neutron stars are briefy trapped and remain out of equilibrium with the cold cores of the stars for 2 to 3 ...
