No-Go Theorem for Singularity Resolution
Zhen-Xiao Zhang, Chen Lan, Yan-Gang Miao
We prove a No-Go theorem for singularity resolution in homogeneous, spatially flat gravitational collapse: within this sector, quantum corrections introduced solely as non-vanishin…
Parametric resonance amplification of gravitational waves in dynamical Chern-Simons gravity
Han-Wen Hu, Chen Lan, Zong-Kuan Guo
Within the effective field theory of dynamical Chern-Simons (dCS) gravity, we study parametric resonance amplification of gravitational waves driven by an oscillating environmental…
Finite Curvature Construction of Regular Black Holes and Quasinormal Mode Analysis
Chen Lan, Zhen-Xiao Zhang, Hao Yang
We develop a class of regular black holes by prescribing finite curvature invariants and reconstructing the corresponding spacetime geometry. Two distinct approaches are employed:…
Branch-dependent ringdown in black-bounce spacetimes: imprints of matter-source ambiguity on quasinormal modes
Hao Yang, Chen Lan
Regular black holes and black-bounce spacetimes frequently emerge in theoretical frameworks beyond general relativity, as well as in general relativity coupled to non-linear source…
The impact of plunging matter on black-hole waveform
Ying-Lei Tian, Hao Yang, Chen Lan +1
In this work, we introduce a novel framework to investigate ringdown gravitational waveforms in the presence of dynamical matter fields outside the horizon of a black hole. We syst…
Quasinormal modes of regular black holes surrounded by skewed dark matter distributions
Chen Lan, Ying-Lei Tian, Hao Yang +2
Regular black holes, nonsingular solutions to gravitational collapse with quantum corrections, offer a compelling alternative to classical black holes with curvature singularities.…
