Pulsed neutron density measurement techniques deploy brief, intense bursts of high-energy neutrons into subsurface formations to probe material density. As neutrons scatter off atomic ...

The X-ray binary system Vela X-1 consists of a neutron star (which contains as much mass as our sun (~10 30 kg), but is very compact and has a radius of ~10 km or so, about the size of a small city) ...

Scientists have discovered a very faraway radio signal that repeats in a regular pattern and sustains for three seconds per pulse—a thousand times longer than most other similar signals. They believe ...

For over 50 years research reactors have supported developments in neutron beam research, new materials, and component integrity testing, and are expected to continue to do so in the coming decades.

Roughly a year ago, astronomers announced that they had observed an object that shouldn’t exist. Like a pulsar, it emitted regularly timed bursts of radio emissions. But unlike a pulsar, those bursts ...

A neutron star manifested among researchers, and it is one that is bizarre for it brings a faint signal that is slow compared to other space objects that are of the same category. It is significantly ...

The Department of Energy's Oak Ridge National Laboratory added a new neutron scattering instrument to its powerhouse of discovery at the Spallation Neutron Source, charting new territory for neutron ...

The Pulsed Fast Reactor (PFR) is designed to study the interaction of neutrons with atomic nuclei. Using a neutron beam, one can investigate nuclear reactions, nuclear excitation, and structure, i.e., ...
