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 ...

Neutron activation analysis is a cutting-edge analytical technique that identifies elements and determines their concentration in numerous different applications. With accurate, fast gamma ...

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 ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of ...

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

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 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.

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

Improved neutron mirrors can increase the efficiency of material analysis in neutron sources such as the ESS, which is being built outside Lund, Sweden. The improved mirror has been developed by ...
