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...

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) ...
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 ...

We show that the sub-TeV spectra of GRB 190114C and GRB 180720B are due to the interaction of high-energy protons with the background photons in the synchrotron self-Compton region and synchrotron region, respectively. The nature of the background photon distributions help us to constrain ...
A state-of-the-art semi-analytic gamma-ray burst (GRB) afterglow model with synchrotron self-Compton (SSC) emission has been applied for the first time for parameter inference using real GRB data. We analyzed the famous GRB 190114C as a case study. GRB 190114C, characterized by its long ...
