MeV Gamma-Ray Lines from Radioactive Nuclei in Magnetar Giant Flares
Wu-Zimo Qiumu, Meng-Hua Chen, Qiu-Hong Chen +4
The rapid neutron-capture process (r-process) is widely regarded as the dominant mechanism responsible for the synthesis of heavy elements in the universe, yet its astrophysical si…
Overview of Ground-based Wide-Angle Cameras array
Liping Xin, Lei Huang, Hongbo Cai +25
As one of the key ground-based facilities of the Chinese-French SVOM mission, the main scientific objectives of the Ground-based Wide Angle Camera array (GWAC) are to detect prompt…
GRB 170519A: Thermal Radiation in an X-ray Flare and Decaying Magnetic Fields for the Early-Time Afterglow
Zi-Min Zhou, Liang-Jun Chen, Rui-Quan Li +5
GRB 170519A was discovered by \emph{Swift}/BAT, and then observed by \emph{Swift}/XRT, \emph{Swift}/UVOT, and ground-based telescopes. We report Lick/KAIT observations of GRB 17051…
The white-light superflares from cool stars in GWAC triggers
Guang-Wei Li, Liang Wang, Hai-Long Yuan +16
M-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-typ…
GRB 221009A/SN 2022xiw: A Supernova Obscured by a Gamma-Ray Burst Afterglow?
De-Feng Kong, Xiang-Gao Wang, WeiKang Zheng +10
We present optical photometry for the afterglow of GRB 221009A, in some respects the most extraordinary gamma-ray burst (GRB) ever observed. Good quality in the R-band light curve…
Spin, inclination, and magnetic field evolution of magnetar population in vacuum and plasma-filled magnetospheres
Jun-Xiang Huang, Hou-Jun Lü, Jared Rice +1
Magnetars are potential energy sources or central engines for numerous transient phenomena in the Universe. How newborn magnetars evolve in different environments remains an open q…
SN 2019tua : A Type IIb Supernova with Multiple Bumps in the Light Curves
Xin-Bo Huang, Xiang-Gao Wang, Long Li +9
We present photometric and spectroscopic observations and analysis of the type IIb supernova (SN) SN 2019tua, which exhibits multiple bumps in its declining light curves between 40…
Searching for Associations Between Short Gamma-ray Bursts and Fast Radio Burst
Ming-Xuan Lu, Long Li, Xiang-Gao Wang +4
The physical origin of fast radio bursts (FRBs) is still unclear. However, young magnetars associated with short-duration gamma-ray bursts (SGRBs) have been thought to be possible…
Magnetic activities and parameters of 43 flare stars in the GWAC archive
Guang-Wei Li, Chao Wu, Gui-Ping Zhou +19
In the archive of the Ground Wide Angle Camera (GWAC), we found 43 white light flares from 43 stars, among which, three are sympathetic or homologous flares, and one of them also h…
Photometric and spectroscopic Studies of Superoutbursts of Three Dwarf Novae Independently Identified by The SVOM/GWAC System in 2018
J. Wang, H. L. Li, L. P. Xin +27
We report our photometric and spectroscopic follow-up observations of the superoutbursts of three dwarf novae (GWAC\,180415A, GWAC\,181017A and GWAC\,181211A) identified independen…
Constraining and Dark Energy with Gamma-Ray Bursts
Z. G. Dai, E. W. Liang, D. Xu
An relationship with a small scatter for current -ray burst (GRB) data was recently reported, where is the beaming-correc…
