Scalar wave dark matter imprints on binary black hole mergers: dependence on field mass and density
Yu-Peng Zhang, Shao-Wen Wei, Yu-Xiao Liu
Dark matter environments can modify binary black hole mergers and imprint their gravitational-wave signals. We perform numerical-relativity simulations of nonspinning binary black…
Spectral Butterfly Effect and Resilient Ringdown in Thick Braneworlds
Hai-Long Jia, Wen-Di Guo, Yu-Peng Zhang +1
The quasinormal mode spectrum is a unique fingerprint linking gravitational-wave observations to extra-dimensional geometry. In this Letter, we show that thick braneworlds exhibit…
Violation of cosmic censorship in Einstein-Maxwell-Scalar models with fractional coupling
Yan-Qing Xu, Rui-Feng Zheng, Yu-Peng Zhang +1
The weak cosmic censorship conjecture plays a foundational role in classical gravity by asserting that spacetime singularities are generically hidden behind event horizons. In this…
Effects of nonlinear interactions on the superradiant instability of charged black holes
Bo-Wen Qin, Yu-Peng Zhang
A Reissner-Nordström black hole (RNBH) enclosed in a cavity is known to be superradiantly unstable to charged scalar perturbations below a critical frequency. Inspired by the emerg…
Self-resonance preheating in deformed attractor models: oscillon formation and evolution
Bao-Min Gu, Yu-Peng Zhang, Fu-Wen Shu +1
It is well known that, in potentials that are quadratic near the minimum but shallower away, such as small- () attractors, the inflaton condensate fragments into loc…
Gravitational equal-area law and critical phenomena of cuspy black hole shadow
Shao-Wen Wei, Chao-Hui Wang, Yu-Peng Zhang +2
The formation of a cusp on a black hole shadow is a striking signature of physics beyond the Kerr paradigm. Using the Konoplya-Zhidenko metric, a general parametrized deformation o…
