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…

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…

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…
