ESA’s Integral observed space for 22 years, uncovering gamma-ray bursts, black holes, and gravitational waves.

The blast lasted for roughly three Earth days ... we can combine direct imaging of the near event horizon regions during gamma-ray flares from particle acceleration events and test theories ...

"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." ...

Early on September 22, 1979, satellites picked up an exceedingly bright double flash in the South Atlantic that has never ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

China and France set off on a mighty explosion toward the universe when they launched the joint Sino-French SVOM mission. Their aim was to study Gamma-ray bursts that coincided with an event where ...

WEST LAFAYETTE, Ind. -- An international team of astronomers has observed extremely rapid bursts of high-energy gamma rays from a distant galaxy, an observation that is challenging how astronomers ...

The U.S. Naval Research Laboratory (NRL), in partnership with NASA's Marshall Space Flight Center (MSFC), has developed ...

This could lead to ecosystem collapse and a potential mass extinction event. Gamma-ray bursts, caused by neutron star mergers, are even more dangerous than supernovas. Their concentrated energy ...

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

They had little encouraging advice to offer. The report did not deal with the damage by radiation (heat, gamma rays, etc.), considered only the blast, which affects a much larger area than the ...

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 ...
