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…

First M87 Event Horizon Telescope Results. VIII. Magnetic Field Structure near The Event Horizon

The Event Horizon Telescope Collaboration

Event Horizon Telescope (EHT) observations at 230 GHz have now imaged polarized emission around the supermassive black hole in M87 on event-horizon scales. This polarized synchrotr…

Revisiting the Relationship between the Long GRB Rate and Cosmic Star Formation History Based on a Large Swift Sample

Jing-Meng Hao, Liang Cao, You-Jun Lu +4

The exact relationship between the long gamma-ray burst (LGRB) rate and the cosmic star formation rate (CSFR) is essential for using LGRBs as cosmological probes. In this work, we…
