An international team of astronomers reports the detection of four new gamma-ray millisecond pulsars using the Murriyang ...

The positioning and the intensity of the gamma ray sources are carefully calculated to ensure that the cancer cells receive enough radiation to kill them whilst the surrounding tissue remains in a ...

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic rays are produced in the jets of microquasars." ...

The isotope used must: be a source of gamma rays so that they pass out through the body to be detected by the gamma camera or GM tube; have very short half-lives - sources used typically have half ...

"This field did not exist before 1989 when the first gamma ray source was detected. At that point, we knew of four sources in the world," said Dave Kieda, professor in the Department of Physics ...

That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

WEST LAFAYETTE, Ind. -- An international team of astronomers has observed extremely rapid bursts of high-energy gamma rays from a distant galaxy, an observation that is challenging how astronomers ...

Ambient gamma radiation is on the rise across the capital with some areas of London affected more than others.

The origin of highest-energy gamma radiation in the nearby radio galaxy Centaurus A could now be localised for the first time ...

In other words, we’ll soon have a record-breaking observatory for studying gamma ray sources—some of the most energetic and mysterious objects in the universe. The observatory’s full name is ...

"The LAT observed a pronounced enhancement in the gamma-ray activity from the direction of the source on 2022-12-08 and on 2023-05-01," the paper reads. LAT monitoring of 3C 216 recorded a strong ...

discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region. This was the first super cosmic ray acceleration source to have ever been authenticated.
