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. When you ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

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

Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint dwarf galaxy embedded in a vast stream of ...

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

A new theoretical framework shows that tidal forces in inspiraling neutron star pairs can be described through oscillation modes, opening a new path to studying ultra-dense matter using gravitational ...

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 ...

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 ...

Researchers have captured the first direct, momentum-resolved evidence that certain lattice vibrations carry measurable ...
