An international team of astronomers, including researchers from the Department of Physics and the Hong Kong Institute for ...

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 ...

A lingering afterglow from a gamma-ray burst may have revealed a new sign of neutron star mergers.

For decades, a theory in physics has postulated the existence of a mirror world whose interaction with our own reality is extremely feeble. The particles in this mirror universe are also thought to be ...

Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied ...

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 ...

Forget earthquakes – the tremors scientists are really excited about are happening thousands of light-years away. By studying “starquakes” in the ultra-dense remnants of collapsed stars, physicists ...

An improved version of a “bottle” experiment lets researchers lower the uncertainty on this important parameter—but a tantalizing discrepancy remains. Figure 1: A cartoon image of the UCN 휏 ...

Airy beam: When an ordinary beam of neutrons strikes the team’s silicon grating, the millions of scored lines on the grating convert the neutrons into an Airy beam with a wavefront that travels along ...

Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists. Neutron star mergers are a treasure trove ...

The National Science Foundation (NSF) has awarded UC Berkeley $10.9 million over five years to expand research on the exotic state of matter inside neutron stars — the dense remains of exploded stars ...
