Astronomers analyzing the gravitational-wave event known as GW200105 report evidence that a black hole and neutron star spiraled into each other on an oval-shaped orbit, rather than the near-circular ...

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions. The ...

Astronomers analyzing the gravitational-wave signal from a 2020 collision between a black hole and a neutron star report evidence that the pair spiraled together on an oval-shaped orbit, rather than a ...

Artist’s impression of an eccentric neutron star–black hole binary. The neutron star’s path is shown in blue and the black hole’s motion in orange as the two objects orbit each other. The eccentricity ...

Dr. Vicky Kalogera, the Daniel I. Linzer Distinguished University Professor in the Department of Physics and Astronomy at Northwestern University will give the 2026 Weinberg Memorial Lecture. The ...

Powerful bright blue cosmic explosions called Luminous Fast Blue Optical Transients could be caused when a black hole or ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery ...
