The MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescope is located in the Canary Islands. Delayed gamma rays from deep space may provide the first evidence for physics beyond current ...
The GLAST gamma-ray telescope was launched into space at 12.05 p.m. local time from Cape Canaveral in Florida today. The instrument is due to orbit some 560 km above the Earth’s surface where it will ...
A new way of creating femtosecond, quasi-monoenergetic gamma-ray pulses has been proposed by Serge Kalmykov at the University of Nebraska-Lincoln and colleagues. Their scheme involves using a stack of ...
An international team of physicists has produced high-intensity gamma beams that have the energy a billion times higher than photons in visible light. These powerful photons significantly exceed all ...

Scientists recreate 'cosmic fireballs' in CERN particle accelerator to hunt for missing gamma-rays
In a first-of-its-kind experiment, scientists have recreated "cosmic fireballs" here on Earth in a particle accelerator.The experiment aimed to investigate the stability of jets of high-temperature ...
The LHAASO observatory has detected gamma rays above 100 TeV from a gamma-ray binary for the first time, challenging current ...
Lorentz-invariance violation (LIV) arises in various quantum-gravity 1,2 theories, but typically at Planck energies that are not accessible on Earth. To test LIV, we must turn to astronomical ...
