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…
The Faintest, Extremely Variable X-ray Tidal Disruption Event from a Supermassive Black Hole Binary?
Mengqiu Huang, Yongquan Xue, Shuo Li +30
Tidal disruption events (TDEs), which occur when stars enter the tidal radii of supermassive black holes (SMBHs) and are subsequently torn apart by their tidal forces, represent in…
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…
The classification of real and bogus transients using active learning and semi-supervised learning
Yating Liu, Lulu Fan, Lei Hu +6
Deep-learning-based methods have been favored in astrophysics owing to their adaptability and remarkable performance and have been applied to the task of the classification of real…
The unluckiest star: A spectroscopically confirmed repeated partial tidal disruption event AT 2022dbl
Zheyu Lin, Ning Jiang, Tinggui Wang +13
The unluckiest star orbits a supermassive black hole elliptically. Every time it reaches the pericenter, it shallowly enters the tidal radius and gets partially tidal disrupted, pr…
