Astronomers analyzing the gravitational-wave event known as GW200105 report evidence that a black hole and neutron star ...

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

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

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.

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.

Physicists at Goethe University in Frankfurt, Germany, have used supercomputer simulations to predict a specific gravitational-wave fingerprint that would confirm quark-gluon plasma forms inside the ...

Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons ...

Gold and other heavy elements are born in some of the universe’s most violent events—but scientists still struggle to understand the nuclear steps that create them. Now, nuclear physicists have ...

Neutron detection and analysis techniques form a critical toolkit in both fundamental research and practical applications across diverse fields. At the heart of these methods is the ability to probe ...

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 ...
