The meaning of GAMMA RAY is a photon emitted spontaneously by a radioactive substance; also : a photon of higher energy than that of an X-ray.
末世灾难之伽马射线暴(Gamma-Ray Burst, GRB) 在广袤无垠、神秘莫测的宇宙舞台上,伽马射线暴(Gamma - Ray Burst,简称GRB)宛如一场惊心动魄的宇宙烟火秀,它是宇宙中已知最为剧烈的爆发现象之一。在转瞬即逝的极短时间内,犹如宇宙深处突然爆发的超级能量炸弹,释放出令人难以想象的巨量伽马射线能量,瞬间照亮宇宙的一...

The brightest gamma-ray burst ever seen as observed by the Swift X-Ray Telescope around an hour after it erupted. (Image credit: NASA/Swift/A. Beardmore (University of Leicester)) One of the most remarkable GRBs observed to date is known as the "brightest of all time," or BOAT, GRB....

The standard deviation of the high voltage during the period of the gamma-ray burst is less than 0.1%, so the electronic circuit is believed to be unaffected by the gamma-ray burst. Full size image Conclusion GRB221009A produced very strong transient signals relative to KGRS background ...

Gamma-ray bursts remain one of the greatest mysteries in astrophysics in spite of recent observational advances and intense theoretical work. Observations of the intensity and spatial distributions of bursts show that their sources are not compatible with any known Galactic population of objects and ...
The Swift X-ray Telescope captured the afterglow of the gamma-ray burst, believed to have been caused by the explosion and subsequent collapse of a star that turned into a black hole. The stunning image (above) was captured about an hour after the gamma-ray was first detected. The b...
Gamma-ray bursts (GRBs) are flashes of high-energy radiation arising from energetic cosmic explosions. Bursts of long (greater than two seconds) duration are produced by the core-collapse of massive stars1, and those of short (less than two seconds) dura
