"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 ...

"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 ...

"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 Crab Nebula is the remnant of a supernova which was observed almost 1000 years ago. Although it corresponds to one of the ...

The photodiode is actually sensitive enough to detect the small amounts of gamma radiation produced from a smoke alarm americium source, and also registers [Alan]’s other more powerful ...

"This is the brightest source of high-energy gamma rays we have ever observed," says James Gaidos ... Another member of the team, John Finley, assistant professor of physics at Purdue, says the ...

A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

Gamma-ray bursts typically emit as much energy in ... of billions of stars and then quickly fades away. What could be the source of these mind-boggling bursts? But it now appears that certain ...

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

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...
