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 ...

In recent years, deep learning gained a lot of attention and made impressive achievements in various applications. Incorporating deep learning in X-ray CT has become a non-reversible trend. In this ...

X-rays make it possible to explore inside human bodies or peer inside objects. The technology used to illuminate the detail in microscopically small structures is the same as that used in familiar ...

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 ...
