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.

Astronomers have confirmed gamma-ray pulsations from PSR J0435+3233, an unusually fast-spinning millisecond pulsar located ...

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, ...

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the ...

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 ...

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 ...

The LHAASO observatory has detected gamma rays above 100 TeV from a gamma-ray binary for the first time, challenging current models of cosmic particle acceleration. (Nanowerk News) The Large High ...

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 ...
