Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

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 physicists. Neutron stars, the remnants of massive stars that have exploded as ...

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

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number ...

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

Space is an endless void of mysterious unknowns, and one particularly alluring enigma concerns the point at which neutron stars take on too much mass and collapse into black holes as a result.

Physicists working with molybdenum-84, a nucleus containing exactly 42 protons and 42 neutrons, have found that this seemingly balanced atom defies one of nuclear physics’ longest-standing ...

Protons in neutron-rich nuclei have a higher average energy than previously thought, according to a new analysis of electron scattering data that was first collected in 2004. The research appears to ...

Fundamental questions that particle physicists have pondered for decades might be answered when a $9.2 million neutron physics beam line is built at the Department of Energy’s Spallation Neutron ...

Parity violation in neutron physics represents a subtle but fundamentally important deviation from mirror symmetry in nuclear interactions. This phenomenon arises from the interplay between the weak ...

So what are ultracold neutrons? Peter Geltenbort: The “thermal neutrons” produced by a research reactor such as ILL have energies of a few hundredths of an electron volt. On average they travel at ...
