宇宙史上最大爆炸!2022年伽马射线暴竟揭开反物质湮灭之谜! 2022年发生的伽马射线暴(Gamma Ray Burst, 简称GRB),堪称“宇宙第二次大爆炸”,或者说,“大爆炸2.0”!这次爆炸不仅震撼了我们的天文设备,还让我们一窥反物 - 黑科技在身边于20240920发布在抖音,已经收获
伽玛射线暴 (Gamma Ray Burst,缩写GRB),又称伽玛暴,是来自天空中某一方向的伽玛射线强度在短时间内突然增强,随后又迅速减弱的现象,持续时间在0.1-1000秒,辐射主要集中在0.1-100MeV的能段。 伽马射线暴理论上是巨大恒星在燃料耗尽时塌缩爆炸或者两颗邻近的致密星体(黑洞或中子星)合并而产生的。如果与太阳相比,它...

Gamma-ray bursts (GRBs) are the most energetic electromagnetic sources in the Universe, releasing 1042–1047 J (refs. 1,2) in prompt gamma-ray radiation. Fifty years after their discovery, the physical origin of this emission is still unknown. Synchrotro
What are some recent exciting gamma-ray-burst developments? There have been a couple of really odd GRBs detected in the last few years. GRB 211211A was a long GRBdetected in December of 2022. Even though it was technically classified as "long," further observations revealed a kilonova, impl...

Astronomers around the world were captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over the Earth on October 9, 2022. The emission came from a Gamma-Ray Burst (GRB) – the most powerful class of explosions in the universe – and ranks...
The gamma-ray burst coded GRB 221009A is the brightest one ever detected since the discovery of this immensely energetic explosion in distant galaxies, the most energetic and luminous electromagnetic event since the Big Bang. In October 2022, it was detected by telescopes from Earth and space, ...
