A cosmic explosion detected on July 4, 2025, began with a 0.4-second gamma-ray burst and then continued glowing in softer ...

A reanalysis of cosmic gamma-ray measurements found no evidence of the tested departures from Lorentz invariance. The researchers tightened limits on specific photon-sector parameters by about a ...

Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst ...

An international team of astronomers, including researchers from the Department of Physics and the Hong Kong Institute for ...

For decades, astronomers have identified collisions between two neutron stars through bursts of gamma rays that can disappear in less than two seconds. But some of these violent encounters may also ...

A researcher identified gamma ray emissions that appear to have originated from dark matter, but other physicists still aren’t convinced. Reading time 4 minutes Astronomers have spent nearly a century ...

Here’s what you’ll learn when you read this story: For nearly a century, scientists have been searching for direct evidence of dark matter—one of the key missing pieces of our theoretical ...

In the quiet laboratories of Bengaluru, a beam of gamma radiation has done something remarkable to an unassuming mulberry plant. Researchers bombarded juvenile twigs of the S54 mulberry variety with ...

Indonesian researchers used gamma radiation and PEG-simulated osmotic stress in hydroponics to identify drought-tolerant ...
