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

"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 ...

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 ...

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 ...

Gamma rays are much shorter in wavelength than visible ... billions of stars and then quickly fades away. What could be the source of these mind-boggling bursts? But it now appears that certain ...

Previous research also indicated that Earth looks down the axis of this system, known as Wolf-Rayet 104, raising concerns ...

The U.S. Naval Research Laboratory (NRL), in partnership with NASA’s Marshall Space Flight Center (MSFC), has developed StarBurst, a small satellite (SmallSat) instrument for NASA's StarBurst ...

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 ...

They belong to a larger group of active galaxies that host active galactic nuclei (AGN), and are the most numerous extragalactic gamma-ray sources. Their characteristic features are relativistic ...

An artist’s concept of the famous Wolf-Rayet 104 “pinwheel star,” previously nicknamed the “Death Star.” New research ...

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 ...
