How gamma-ray bursts(GRBs),the most powerful and spectacular explosions known in the universe since the Big Bang,fuel their high-energy radiations?What kind of physical reactions can trigger and sustain such violent,e...
Gamma-ray bursts (GRBs) are extremely powerful explosions that have been traditionally classified into two categories: long bursts (LGRBs) with an observed duration T90 > 2 s, and short bursts (SGRBs) with ...

Gamma-ray bursts(GRBs)exhibit powerful radiation and relativistic jets similar to blazars.However,the central engine of GRBs remains unknown.In this paper,we use the fundamental plane to analyze a sample of GRBs with ...

Extra-galactic gammaray sources,such as gamma-ray bursts,active galactic nuclei,starburst galaxies,are interesting and important targets for LHAASO observations.In this chapter,the prospects of detecting these sources...
Insight-HXIUT is China's hrst X-ray astronomy satellite.It was launched on 15 June 2017 and is currently in service smoothly.Insight-HXMT has been used to scan the Galactic plane repeatedly,making pointing observation...

Rapid spectroscopy of GRB afterglows is an important and hard task.Based on the archival XSGRB spectral database,we here perform a pilot study on the afterglow's spectroscopy in the forthcoming SVOM era in two aspects...
The recent finding that gravitational waves (GW170817) traveled at the same speed as electromagnetic (EM) waves (GRB 170817A) from a binary neutron star merger does not necessarily mean that they traveled throughout t...
Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. Alt-hough the exact mechanism behind these explosions remains elusive, GRBs hold great promise as cosmological probes for two main reasons: the...
