Clock-noise subtraction in geometric time-delay interferometry for space-based gravitational-wave parameter estimation
Rui Luo, Pan-Pan Wang, Zi-Jiang Yang +2
Millihertz gravitational-wave observations with space-based interferometers require time-delay interferometry (TDI) observables whose residual instrumental noise is sufficiently co…
Sensitivity of black hole spectral instability to ultraviolet perturbations
Ramin G. Daghigh, Michael D. Green, Guan-Ru Li +3
Black hole quasinormal modes are known to exhibit spectral instability under ultraviolet perturbations of the effective potential. In the present work, we investigate the sensitivi…
Ringdown Signatures of Dehnen Dark Matter Halos: Fluid Modes and Detectability with Space-Based Detectors
Manjia Liang, Minghui Du, Qing Diao +5
In this work, we investigate the feasibility of using ringdown waveforms from supermassive black holes immersed in dark-matter halos to extract both the intrinsic black-hole parame…
A metric solution for rotating black holes embedded in dark matter halos with central spikes
Rui-Hong Yue, Yu-Qian Zhao, Wei-Liang Qian
We propose an analytic metric describing rotating black holes surrounded by generic dark matter halos. This metric is an exact solution of the field equations that incorporates a d…
QNM families: classification and competition
Zhen-Hao Yang, Liang-Bi Wu, Xiao-Mei Kuang +1
The perturbation spectra of black holes beyond standard vacuum black hole solutions within generalrelativity (GR) may exhibit complex structures with long-lived modes. This usually…
Continued fraction method for high overtone quasinormal modes in effective potentials with discontinuity
Guan-Ru Li, Jodin C. Morey, Wei-Liang Qian +4
In this study, we extend Leaver's continued fraction method to evaluate black hole quasinormal modes (QNMs) in systems where the effective potential exhibits a discontinuity. Besid…
