Study of the intrinsic resolution of LaBr3(Ce,Sr) and NaI(Tl) crystals
Peiyi Feng, Xilei Sun, Zhenghua An +4
The Gravitational wave burst high-energy Elec?tromagnetic Counterpart All-sky Monitor (GECAM) utilizes a large number of LaBr3 and NaI(Tl) crystals as sensitive materials for its g…
Performance of the Gamma-ray Transient Monitor at the IHEP Electron-Beam Facility
Pei-Yi Feng, Zheng-Hua An, Yu-Hui Li +26
Gamma-Ray Transient Monitor (GTM) is an all-sky monitor onboard the Distant Retrograde Orbit-A (DRO-A) satellite, with the scientific objective of detecting gamma-ray bursts in the…
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…
