O5 dark-siren forecasts for modified GW propagation: background robustness of the posterior
Zhaorui Zhang, Hong-Bo Jin
The paper studies how assumptions about the matter density (Ωₘ) affect the inference of the modified gravitational‑wave propagation parameter (ε) from binary‑black‑hole dark‑siren…
Solving Hamiltonian Constraint Equation with Physics-Informed Neural Networks
Yu-Chen Zhou, Hao Ma, Zhoujian Cao +6
Numerical relativity (NR), solving Einstein equation numerically, plays an important role in source modelling for gravitational wave astronomy. Traditional methods for NR including…
Probing Gravitational Quantum Field Theory through Polarization Fingerprints of Gravitational Waves
Cong Xu, Hong-Bo Jin, Yue-Liang Wu
Gravitational Quantum Field Theory (GQFT) has been proposed as a candidate framework to reconcile general relativity with quantum field theory, and a distinctive imprint on gravita…
BBN constraints on primordial black holes with a continuous memory-burden crossover
Xuan-Yu Zhang, Mei-Ting Yang, Hong-Bo Jin
Light primordial black holes (PBHs) are disfavored as dark matter if they evaporate through standard Hawking radiation alone. The memory-burden effect can extend their lifetimes by…
Finite-Window Centered Organization of Neighboring Poles
Yuye Wu, Hong-Bo Jin
Near-degenerate resonance poles arise widely in open-wave systems. For gravitational-wave ringdowns, inference is performed on finite time windows where neighboring quasinormal mod…
Pair-Dependent Drift of Kerr Neighboring-Overtone Gap Minima
Yuye Wu, Hong-Bo Jin
We study adjacent Kerr quasinormal-mode overtones under a spin scan with overtone labels held fixed, using a public Leaver-type solver on a uniform grid. The observable is the modu…
