Discovery of a Featureless Tidal Disruption Event at z~1 with the Wide Field Survey Telescope
Jiazheng Zhu, Zelin Xu, Ning Jiang +31
We report the discovery of tidal disruption event (TDE) WFST250820mmsw/AT2025wet by the 2.5-meter Wide Field Survey Telescope (WFST). It exhibits a blue nuclear flare throughout th…
A Tidal Disruption Event from an Intermediate-mass Black Hole Revealed by Comprehensive Multi-wavelength Observations
Jialai Wang, Mengqiu Huang, Yongquan Xue +12
Tidal disruption events (TDEs) occur when a star crosses the tidal radius of a black hole (BH) and is ripped apart, providing a powerful way to probe dormant BHs over a wide mass r…
Ultraviolet Spectral Evidence for Ansky as a Slowly Evolving Featureless Tidal Disruption Event with Quasiperiodic Eruptions
Jiazheng Zhu, Ning Jiang, Yibo Wang +13
X-ray quasi-periodic eruptions (QPEs) are rare and enigmatic phenomena that increasingly show a connection to tidal disruption events (TDEs). However, the recently discovered QPEs…
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…
Insights from the "Red devil" AT 2022fpx: A Dust-reddened Family of Tidal Disruption Events Excluded by Their Apparent Red Color?
Zheyu Lin, Ning Jiang, Yibo Wang +5
We report unnoticed but intriguing features in the peculiar nuclear transient AT 2022fpx, and investigate its type. These features include the constantly red optical color of $g-r>…
Unveiling the Cosmic Dance of Repeated Nuclear Transient ASASSN-14ko: Insights from Multiwavelength Observations
Shifeng Huang, Tinggui Wang, Ning Jiang +15
ASASSN-14ko is a periodically repeating nuclear transient. We conducted high-cadence, multiwavelength observations of this source, revealing several recurrent early bumps and rebri…
