A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

Some of the X-ray radiation circulating in the cavity is allowed to escape downstream, providing a beam of monochromatic and coherent X-ray pulses. They have called their system X-ray Free-Electron ...

With PFITRE, Brookhaven scientists achieve breakthrough 3D imaging in nanoscale X-ray tomography, combining AI and physics for superior clarity and precision.

X‐ray binaries serve as natural laboratories for investigating the extreme physics of accretion and relativistic phenomena. These systems, comprising a compact object – typically a black hole or ...
