Compact camera The Seracam portable gamma camera is mounted on a trolley with an articulated arm for clinical use. A single cable connects to a power supply and a computer for data acquisition and ...

Gamma rays belong to the same family as light, x-rays, ... to catch the first x-ray afterglow of a burst as soon as possible. The latest of these satellites, called Swift, ...

Shrouded in mystery for decades, gamma-ray bursts are the brightest explosions since the Big Bang and emerge from only the most violent cosmic events.

Isolated gamma-ray bursts may come from neutron star mergers in faint galaxies as distant as 10 billion light-years away.

While the burst (its formal name is GRB 221009A) is probably not the brightest to ever occur, it is “likely the brightest burst at X-ray and gamma-ray energies to occur since human civilization ...

On Oct. 9, 2022, Swift’s X-Ray Telescope captured the afterglow of the brightest gamma-ray burst every recorded, called GRB 221009A. Credit: NASA/Swift/A. Beardmore (University of Leicester) ...

This detonation is the brightest burst at X-ray and gamma-ray energies since human civilization began. It is 70 times brighter than any observed before.

Gamma-ray flares from blazars can be accompanied by high-energy neutrino emission. To better understand this phenomenon, an international research team has statistically analyzed 145 bright blazars.
