A “beautiful effect” predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar – a neutron star featuring a powerful magnetic fie...
An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star like cotton candy as it pulls in material from a nearby star. As the disk spins, it whips u...
Russia's Rosatom and China's Atomic Energy Authority (CAEA) have signed a Comprehensive Programme for Long-Term Cooperation in the field of fast-neutron reactors and closing the nuclear fuel cycle.
When the most massive stars die, they collapse under their own gravity and leave behind black holes. When stars that are a bit less massive die, they explode in supernovas and leave behind dense, dead...
On April 25, NSF's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears to be a crash between two neutron s...
Three months of observations with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) have allowed astronomers to zero in on the most likely explanation for what happened in the af...
Advances continue to be made in hard x-ray, gamma-ray, neutron detectors and associated technologies for spectroscopy and imaging of these energetic photons and particles. Many types of position and e...
For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first tim...
Two months ago, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) notified astronomers around the world of the possible detection of gravitational waves from the merger of two ne...
When a pair of superdense neutron stars collided and potentially formed a black hole in a galaxy 130 million light-years from Earth, they unleashed not only a train of gravitational waves but also an ...
2017SPIE硬X射线,伽玛射线和中子探测器物理专题会议(Hard X-Ray,Gamma-Ray,and Neutron Detector Physics XIX)。
The Gordon Research Seminar (GRS) on Neutron Scattering is a unique forum which is intended to bring together graduate students, post-docs and early-career faculty with comparable levels of experience...
With major new investments in infrastructure for neutron science in the US, Europe, Asia, and Australia either completed or in advanced planning, our capabilities for understanding new materials using...
Breakthrough energy resolution, R(662keV) <4%, has been achieved with a transparent ceramic oxide scintillator, Cerium-doped Gadolinium Yttrium Gallium Aluminum Garnet, or GYGAG(Ce), by optimizing fab...
Some neutron stars may rival black holes in their ability to accelerate powerful jets of material to nearly the speed of light, astronomers using the Karl G. Jansky Very Large Array (VLA) have discove...
