Searching for Type Ia Supernovae in the Dark Energy Spectroscopic Instrument
Xiaoyu Zhuang, Song Ran, Dezheng Meng +9
With the development of large-scale photometric surveys, an increasing number of supernova candidates are being discovered, leading to a rapidly growing demand for supernova spectr…
A Unified Timescale Relation for Quasi-Periodic Eruptions and Repeated Nuclear Transients
Shifeng Huang, Tinggui Wang, Ning Jiang +9
Quasi-periodic eruptions (QPEs) and recurrent nuclear transients (RNTs) exhibit recurrent high-amplitude flares from galactic nuclei, yet their characteristic timescales remain poo…
Two Earliest Optical-UV Tidal Disruption Events Hidden in the SDSS DR7 Catalog Unveiled by the Transformer-Based Spectrum Classifier
Ranfang Zheng, Zheyu Lin, Xu Kong +3
Optical spectroscopic features are decisive in the current identification of optical-UV tidal disruption events (TDEs). Regarding that the TDE estimated occurrence rate is $10^{-5}…
Characterizing and spectrally modeling embedded FUor eruptions in the near-infrared
Jiaxun Li, Tinggui Wang, Zheyu Lin
Context. Episodic accretion in young stellar objects (YSOs) is thought to play a critical role in addressing the "luminosity problem" associated with star formation. However, optic…
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…
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…
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…
The Relation of the hyperluminous Dust-obscured Quasars up to
Yibin Luo, Lulu Fan, Weibin Sun +6
Hot dust-obscured galaxies (Hot DOGs) are a rare population of hyperluminous dust-obscured quasars discovered by the Wide-field Infrared Survey Explorer (WISE) all-sky survey. The…
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…
Bipolar blobs as evidence of hidden AGN activities in the low-mass galaxies
Yao Yao, Enci Wang, Zhicheng He +4
We report the evidence of a hidden black hole (BH) in a low-mass galaxy, MaNGA 9885-9102, and provide a new method to identify active BH in low mass galaxies. This galaxy is origin…
Ly imaging around the hyperluminous dust-obscured quasar W22460526 at
Yibin Luo, Lulu Fan, Yongming Liang +10
Hot dust-obscured galaxies (Hot DOGs) are a population of hyperluminous, heavily obscured quasars discovered by the \emph{Wide-field Infrared Survey Explorer} (\emph{WISE}) all-sky…
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…
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…
ASASSN-18ap: A Dusty Tidal Disruption Event Candidate with an Early Bump in the Light Curve
Yibo Wang, Tingui Wang, Ning Jiang +7
We re-examined the classification of the optical transient ASASSN-18ap, which was initially identified as a supernova (SNe) upon its discovery. Based on newly emerged phenomena, su…
Dwarf galaxies with the highest concentration are not thicker than ordinary dwarf galaxies
Lijun Chen, Hong-Xin Zhang, Zesen Lin +5
The formation mechanism of high-concentration dwarf galaxies is still a mystery. We perform a comparative study of the intrinsic shape of nearby low-mass galaxies with different st…
