Identifying Kilonovae in the Presence of Optical Afterglow for the Wide Field Survey Telescope
Huan Yang, Zhengyan Liu, Liang-Duan Liu +2
Identifying kilonovae associated with binary neutron star mergers is often complicated by the presence of a dominant synchrotron afterglow. In this work, we evaluate the performanc…
Exploring Hierarchical Merger Scenarios for GW241011 and GW241110
Lei He, Liang-Gui Zhu, Zheng-Yan Liu +4
GW241011 and GW241110 are asymmetric binary black hole mergers with rapidly spinning primaries, unequal component masses, and nonzero spin--orbit tilts, making them natural candida…
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…
Electromagnetic Follow-up of the Sub-Solar Mass Gravitational Wave Candidate S251112cm: Kilonova Constraints and a Coincident IIb Supernova
Xander J. Hall, Tomas Ahumada, Julius Gassert +25
On November 12th, 2025 the LIGO--Virgo--KAGRA (LVK) collaboration reported gravitational waves (GWs) from a compact object merger candidate (S251112cm) with at least one sub-solar…
Searching for Electromagnetic Counterpart Candidates to GW231123
Lei He, Liang-Gui Zhu, Zheng-Yan Liu +14
The detection of GW231123, a gravitational-wave (GW) event with exceptionally massive and rapidly spinning black holes, suggests the possible formation within an active galactic nu…
Tracing the light: Identification for the optical counterpart candidates of binary black-holes during O3
Lei He, Zhengyan Liu, Rui Niu +9
The accretion disks of active galactic nuclei (AGN) are widely considered the ideal environments for binary black hole (BBH) mergers and the only plausible sites for their electrom…
A Systematic Search for Active Galactic Nucleus Flares in ZTF Data Release 23
Lei He, Zheng-Yan Liu, Rui Niu +13
Active galactic nuclei (AGNs) are known to exhibit stochastic variability across a wide range of timescales and wavelengths. AGN flares are extreme outbursts that deviate from this…
LVK S241125n: Massive Binary Black Hole Merger Produces Gamma Ray Burst in Active Galactic Nucleus Disk
Shu-Rui Zhang, Yu Wang, Ye-Fei Yuan +6
Recently, the gravitational-wave (GW) event S241125n, detected by LIGO/Virgo/KAGRA (LVK), has been reported to coincide with a candidate detected by Swift-BAT/GUANO and an X-ray ca…
A constraint on superheavy elements of the GRB-kilonova AT 2023vfi
Zhengyan Liu, Ji-an Jiang, Wen Zhao
The discovery of the kilonova (KN) AT 2017gfo, accompanying the gravitational wave event GW170817, provides crucial insight into the synthesis of heavy elements during binary neutr…
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…
Could the inter-band lag of active galactic nucleus vary randomly?
Zhen-Bo Su, Zhen-Yi Cai, Jun-Xian Wang +18
The inter-band lags among the optical broad-band continua of active galactic nuclei (AGNs) have been intensively explored over the past decade. However, the nature of the lags rema…
Kilonova-Targeting Lightcurve Classification for Wide Field Survey Telescope
Runduo Liang, Zhengyan Liu, Lei Lei +1
With the enhancement of sensitivity of Gravitational Wave (GW) detectors and capabilities of large survey facilities, such as Vera Rubin Observatory Legacy Survey of Space and Time…
Measuring the Hubble constant with coalescences of binary neutron star and neutron star-black hole: bright sirens \& dark sirens
Jiming Yu, Zhengyan Liu, Xiaohu Yang +4
The observations of gravitational wave (GW) provide us a new probe to study the universe. GW events can be used as standard sirens if their redshifts are measured. Normally, starda…
