Guanlin Li,Chao Wu,Guilin Zhou,Chen Yang,Huali Li,Jie Chen,Li-Ping Xin,Jian Wang,Hasitieer Haerken,Chao Ma,H. Cai,Xuhui Han,Lei Huang,Xiao-Meng Lu,J. Bai,Xukang Zhang,Xinli Hao,Xiang-Yu Wang,Zi-Gao Dai,En-Wei Liang,X.-F. Meng,Jian-Yan Wei +21 more
TL;DR: In the archive of the Ground Wide Angle Camera (GWAC), the authors found 43 white light flares from 43 stars, among which, three are sympathetic or homologous flares, and one of them also has a quasi-periodic pulsation with a period of $13.0\pm1.5$ minutes.
Accretion and Host-Galaxy Properties of 14 New “Changing-Look” Active Galactic Nuclei Identified from the SDSS-V Survey
TL;DR: In this paper , the authors reported the identification of 14 new active galactic nucleus (AGN) exhibiting spectral-type changes on a timescale of $z < 0.5$.
White-light Superflare and Long-term Activity of the Nearby M7-type Binary EI Cnc Observed with GWAC System
Huali Li,Jian Wang,Li-Ping Xin,J. Bai,Xuhui Han,H. Cai,Lei Huang,Xiao-Meng Lu,Yu Qiu,Chao Wu,Guanlin Li,Jinsong Deng,Dawei Xu,Yuan-Gui Yang,Xiang Gao Wang,En-Wei Liang,Jian-Yan Wei +16 more
TL;DR: A superflare was detected in the nearby M7-type binary EI Cnc, with a lower flare energy limit of 3.3 × 10^32 erg, and 27 additional flares observed, reinforcing the trend of enhanced superflare activity in cooler stars and establishing a common flare mechanism for M-type to solar-like stars.

TL;DR: In this paper , the authors reported a stellar superflare detected with the Ground Wide Angle Camera (GWAC), along with rapid follow-ups with the F60A, Xinglong 2.16m and LCOGT telescopes.
Photometric Observations of Flares on AD Leo from GWAC-F30 and TESS
TL;DR: In this paper , the authors observed active M dwarf star AD Leo for 146 hours in photometry by GWAC-F30 and also analyzed 528 hr of photometric data of the star from the Transiting Exoplanet Survey Satellite (TESS).
