WFST Astrometric Calibration -- I. Modeling Global Geometric Distortion with Zernike Polynomials
Chao Yang, Min Fang, Xian Zhong Zheng +21
Accurate modeling of geometric distortion is essential for precise astrometric calibration in wide-field imaging surveys. We present a self-calibration method based on Zernike poly…
Illuminating the Mass Gap Through Deep Optical Constraint on a Neutron Star Merger Candidate S250206dm
Zhengyan Liu, Zelin Xu, Ji-an Jiang +35
The gravitational wave (GW) event S250206dm, as the first well-localized neutron star merger candidate potentially located in the mass gap, presented a unique opportunity to probe…
Asteroseismology study of a new faint ZZ Ceti J053009.62+594557.0 discovered in WFST
Yang Yonghui, Guo Jincheng, Lin Jie +16
In this work, we present a detailed asteroseismological analysis of WFST J053009.62+594557.0, a newly discovered faint pulsating white dwarf by the Wide Field Survey Telescope (WFS…
TTC: Transformer-based TDE Classifier for the Wide Field Survey Telescope (WFST)
Ranfang Zheng, Zheyu Lin, Xu Kong +22
We propose the Transformer-based Tidal disruption events (TDE) Classifier (\texttt{TTC}), specifically designed to operate effectively with both real-time alert streams and archiva…
A Star's Death by a Thousand Cuts: The Runaway Periodic Eruptions of AT2023uqm
Yibo Wang, Tingui Wang, Shifeng Huang +37
Stars on bound orbits around a supermassive black hole may undergo repeated partial tidal disruption events (rpTDEs), producing periodic flares. While several candidates have been…
A Glimpse of Satellite Galaxies in the Milky Way with the 2.5-meter Wide Field Survey Telescope (WFST): Bootes III and Draco
Chao Yang, Zhizheng Pan, Min Fang +34
We carry out deep imaging of the Milky Way satellite galaxies, Bootes III and Draco, with WFST as one pilot observing program to demonstrate the capability of WFST. Combining catal…
A pilot survey on globular clusters with the Wide Field Survey Telescope (WFST)
Zhen Wan, Lulu Fan, Xuzhi Li +19
We carry out an imaging survey of six globular clusters (GCs) with a limit magnitude to 22 mag at the 5 sigma level, down to the main sequence stars of the respective cluster, as o…
Minute-cadence observations on Galactic plane with Wide Field Survey Telescope (WFST): Overview, methodology and early results
Jie Lin, Tinggui Wang, Minxuan Cai +26
As the time-domain survey telescope of the highest survey power in the northern hemisphere currently, Wide Field Survey Telescope (WFST) is scheduled to hourly/daily/semi-weekly sc…
GRB 240529A: A Tale of Two Shocks
Tian-Rui Sun, Jin-Jun Geng, Jing-Zhi Yan +66
Thanks to the rapidly increasing time-domain facilities, we are entering a golden era of research on gamma-ray bursts (GRBs). In this Letter, we report our observations of GRB 2405…
AT2023lli: A Tidal Disruption Event with Prominent Optical Early Bump and Delayed Episodic X-ray Emission
Shifeng Huang, Ning Jiang, Jiazheng Zhu +42
High-cadence, multiwavelength observations have continuously revealed the diversity of tidal disruption events (TDEs), thus greatly advancing our knowledge and understanding of TDE…
