该研究的作者Masahiro Teshima表示:“我们从理论上预测了能量在TeV范围内的高能GRB。天文学家在过去15年一直在搜寻了如此强大的伽马射线暴。我和我的国际团队很自豪地宣布,发现了第一个如此强大的伽马射线暴,其能量高达1TeV,是迄今为止从GRB探测到的最高能量的光子。” 该事件名为GRB190114C,它已于今年1月14日被...
伽马射线暴GRB 190114C伽马射线暴(Gamma-ray bursts,GRB)是宇宙中最强大的能量爆发之一。它们发出的大部分能量是伽马射线,这种射线比我们用眼睛看到的可见光能量要大得多。哈勃的观测表明,GRB 190114C这一特殊的爆发显示出异常强大的辐射,因为这颗正在坍塌的恒星正处于50亿光年之外的一个明亮星系的稠密核心。去...

GRB 190114C is the first binary-driven hypernova (BdHN) fully observed from the initial supernova appearance to the final emergence of the optical SN signal. It offers an unprecedented testing ground for the BdHN theory and it is here determined and further extended to additional gamma-ray bur...

We present radio and optical afterglow observations of the TeV-bright long gamma-ray burst 190114C at a redshift of z = 0.425, which was detected by the Major Atmospheric Gamma Imaging Cherenkov telescope. Our observations with Atacama Large Millimeter/submillitmeter Array, Australia Telescope ...
In this contribution I will describe the main results and the theoretical interpretations that have been derived from the multi-wavelength dataset of GRB190114C. In particular, the description of the TeV component detected by the MAGIC telescopes as produced via the Synchrotron Self-Compton (SSC) ...
