Hierarchical Black Hole Mergers in Nuclear Star Clusters: A Combined Dynamical-Secular Channel for GW231123-like Events
Bin Liu, Dieran Wang, Dong Lai
The paper proposes that hierarchical (second‑generation) black hole mergers like GW231123 can arise in nuclear star clusters through combined binary‑single interactions and secular…
Tidal capture and repeating partial tidal disruption events of giant stars
Di Wang, Fa-Yin Wang
When an object is scattered near a supermassive black hole (SMBH), tidal oscillations excited within it reduce its orbital energy, leading to capture by the SMBH. This process, cal…
Hubble constant measurement from QPEs as electromagnetic counterparts to extreme mass ratio inspirals
Yejing Zhan, Di Wang, Shuang-Xi Yi +1
Gravitational waves (GWs) accompanied by electromagnetic (EM) counterparts provide a novel methodology to measure the Hubble constant (), known as bright sirens. However, the…
Spin and Obliquity Distributions of Low-mass Planets Shaped by Dynamical Instability
Dieran Wang, Jiaru Li, Dong Lai
Exoplanetary systems hosting multiple low-mass planets are thought to have experienced dynamical instability, during which planet-planet collisions and mergers occur; these collisi…
