GECAM discovery of a peculiar magnetar X-ray burst (MXB 221120) from SGR J1935+2154 associated with a fast radio burst
Wen-Jun Tan, Yue Wang, Chen-Wei Wang +50
Fast radio bursts (FRBs) are enigmatic cosmic transients of millisecond duration observed in the radio band. The identification of FRB-associated magnetar X-ray bursts (MXBs) from…
The Origin of Cross-Energy-Similar FRED Profiles in Gamma-Ray Bursts Pulses
Shu-Xu Yi, Chen-Wei Wang, Shao-Lin Xiong +5
To understand the physical mechanisms underlying the prompt emission of gamma-ray bursts (GRB), single FRED (Fast-Rise-Exponential-Decay) profile GRBs serve as an ideal sample, as…
Geometric Search for Hawking Radiation from Nearby Primordial Black Holes
Shuo Xiao, Shuang-Nan Zhang
A nearby primordial-black-hole (PBH) evaporation burst would produce a curved gamma-ray wavefront, leading to detectable departures from plane-wave inter-satellite delays. We intro…
GECAM discovery of the second FRB-associated Magnetar X-ray Burst from SGR J1935+2154
Chen-Wei Wang, Shao-Lin Xiong, Yue Wang +47
Fast radio burst (FRB) is mysterious phenomenon with millisecond-duration radio pulses observed mostly from cosmological distance. The association between FRB 200428 and a magnetar…
Systematic Study of the Simultaneous Events Detected by GECAM
Yang-Zhao Ren, Feng-Rong Zhu, Shao-Lin Xiong +45
GECAM is a constellation of all-sky monitors in hard X-ray and gamma-ray band primarily aimed at high energy transients such as gamma-ray bursts, soft gamma-ray repeaters, solar fl…
Brightest GRB flare observed in GRB 221009A: bridge the last gap between flare and prompt emission in GRB
Zheng-Hang Yu, Chen-Wei Wang, Shao-Lin Xiong +46
Flares are usually observed during the afterglow phase of Gamma-Ray Bursts (GRBs) in soft X-ray, optical and radio bands, but rarely in gamma-ray band. Despite the extraordinary br…
