A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron beam and an ultrahigh intensity laser pulse using the 4-Petawatt laser.
Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to create compact gamma-ray sources that are simultaneously brighter, sharper, ...
Today, the European Space Agency's gamma-ray telescope ends its observations. During its 22 years in space, Integral has reshaped our view of the most dramatic events in the universe. The high-energy ...

NASA’s Fermi telescope just caught what may be the first gamma-ray signal from a superluminous supernova — one of the most extreme blasts in the known universe
A stellar explosion that briefly outshone its entire host galaxy may have left behind a calling card no superluminous supernova has ever produced before: a burst of high-energy gamma rays detected by ...
Above the cloud tops, thunderstorms throb with a complex, frenetic light show of high-energy radiation. A view from a retrofitted spy plane soaring at 20 kilometers up revealed storms glowing and ...
Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...
On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. The source was a gamma-ray ...
