Skoltech researchers used the resources of the university's Zhores supercomputer to study a new method of generating gamma-ray combs for nuclear and X-ray photonics and spectroscopy of new materials.

The pairs should then scatter on the cosmic microwave background to generate lower-energy gamma rays—yet these have not been captured by gamma-ray space telescopes, such as the Fermi satellite. Up to ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...
