Gamma-ray bursts are useful measurement tools in cosmology — with a few caveats. The main one is that it takes the observation of a tremendously large number of GRBs to draw meaningful ...

IN his article on the isotropic gamma ray background, Cheng1 presents instructive calculations of the production and propagation of inverse Compton gamma rays in an expanding universe. The latter ...

Gamma-ray flares from blazars can be accompanied by high-energy neutrino emission. To better understand this phenomenon, an international research team has statistically analyzed 145 bright blazars.

Chinese space telescopes accurately measure brightest gamma-ray burst ever detected Peer-Reviewed Publication. Chinese Academy of Sciences Headquarters ...

Using a combination of telescopes, astronomers have characterized the closest supernova linked to a fast X-ray transient. The ...

Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block.

We are also creating a table of the past gamma-ray bursts and the observations of the ozone layer and trying to see if they match,” he said. Nature Communications, 2023. DOI: 10.1038/s41467-023 ...

This gamma ray conversion, astrophysicist Tim Linden said, probably takes place 100 to 1,000 kilometers below the sun’s surface, where the magnetic field is strong enough to turn the cosmic rays ...

A huge surge of gamma-ray energy from space caused electric currents to flow through the surface of the Earth on October 9, scientists have said.. This gamma-ray burst, named GRB221009A, is the ...

"Gamma-ray bursts can be seen at incredibly large distances ... have had sufficient time in the 13.8 billion-year-old universe to form if the spread of matter is homogeneous and isotropic. ...
