The PSR J0435+3233 Triple System
Z. L. Yang, J. L. Han, Y. Yan +9
The detailed evolution of triple star systems is complicated and poorly known. Based on the optical/infrared and gamma-ray archived data, we identified that the pulsar, PSR~J0435+3…

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…
