Using NASA's Fermi Gamma-ray Space Telescope, Chinese astronomers have observed a gamma-ray binary system known as PSR ...

Integral’s latest survey of the gamma-ray universe continues to change the way astronomers think of the high-energy cosmos. With over seventy percent of the sky now observed by Integral, astronomers ...

There is a gamma-ray lighthouse shining from the edge of our universe. Astronomers have discovered it using ESA’s orbiting gamma-ray observatory, Integral. Now, they must work hard to understand it.

For the first time a gamma-ray burst (GRB) has been observed simultaneously in the X-ray and in the very high energy gamma ray band. The MAGIC telescope at La Palma, Canary Islands, observed the ...

The advent of new radio surveys as the VLA Sky Survey (VLASS) and Rapid ASKAP Continuum Survey (RACS), realized with the latest generation radio telescopes, is opening new opportunities for the study ...

Gamma-ray binaries represent one of the most dynamic and intriguing classes of high-energy astrophysical systems. These binaries typically consist of a massive star and a compact object – often a ...

After the initial discovery, astronomers debated where these bursts of gamma radiation were coming from—a critical clue for what’s powering them. Some thought that such bright sources must be nearby, ...
