Depending on the circumstances you find yourself in, a Geiger counter can be a tremendously useful tool. With just a click or a chirp, it can tell you if any invisible threats lurk. But a Geiger ...

Gamma-ray detection and analysis techniques have become indispensable in both basic and applied nuclear research. Modern systems utilise semiconductor detectors – notably high-purity germanium (HPGe) ...

A new IAEA coordinated research project (CRP D12015) will apply gamma-ray spectrometry and digital technologies such as drones, satellite imagery and advanced analytics for precise soil assessment to ...

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

Sarah Dalessi, a fifth-year student in the College of Science at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, is the lead author of a paper published in ...

This study is led by Prof. Shaolin Xiong (Institute of High Energy Physics, Chinese Academy of Sciences) and Prof. Jirong Mao (Yunnan Observatories, Chinese Academy of Sciences) and Prof. Shuang-Nan ...

The brightest gamma-ray burst in 10,000 years that swept over Earth last year blinded all of NASA's flagship gamma-ray missions. A tiny Eastern European cubesat, however, rose to the occasion, taking ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

In October 2022, astronomers were stunned by what was quickly dubbed the BOAT -- the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA's Fermi ...

Astronomers have caught a cosmic explosion doing something it was never supposed to do, firing off three powerful gamma-ray bursts from the same source within hours. The triple outburst is forcing ...
