Merging black holes with Cauchy-characteristic matching: Computation of late-time tails
Sizheng Ma, Mark A. Scheel, Jordan Moxon +5
Cauchy-characteristic matching (CCM) is a numerical-relativity technique that solves Einstein's equations on an effectively infinite computational domain, thereby eliminating syste…
Overtones and Nonlinearities in Binary Black Hole Ringdowns
Matthew Giesler, Sizheng Ma, Keefe Mitman +11
Using high-accuracy numerical relativity waveforms, we confirm the presence of numerous overtones of the , quasinormal mode early in the ringdown of binary black hole…
Echoes from beyond: Detecting gravitational-wave quantum imprints with LISA
Nils Deppe, Lavinia Heisenberg, Henri Inchauspé +7
We assess the prospects for detecting gravitational wave echoes arising due to the quantum nature of black hole horizons with LISA. In a recent proposal, Bekenstein's black hole ar…
Quadratic Mode Couplings in Rotating Black Holes and Their Detectability
Neev Khera, Sizheng Ma, Huan Yang
Quadratic quasinormal modes encode fundamental properties of black hole spacetimes. They are also one of the key ingredients of nonlinearities of General Relativity in the ringdown…
Einstein-Klein-Gordon system via Cauchy-characteristic evolution: Computation of memory and ringdown tail
Sizheng Ma, Kyle C. Nelli, Jordan Moxon +5
Cauchy-characteristic evolution (CCE) is a powerful method for accurately extracting gravitational waves at future null infinity. In this work, we extend the previously implemented…
Nonlinear effect of absorption on the ringdown of a spinning black hole
Taillte May, Sizheng Ma, Justin L. Ripley +1
The ringdown gravitational wave signal arising e.g., in the final stage of a black hole binary merger, contains important information about the properties of the remnant, and can p…
Imprints of Changing Mass and Spin on Black Hole Ringdown
Hengrui Zhu, Frans Pretorius, Sizheng Ma +8
We numerically investigate the imprints of gravitational radiation-reaction driven changes to a black hole's mass and spin on the corresponding ringdown waveform. We do so by compa…
The excitation of quadratic quasinormal modes for Kerr black holes
Sizheng Ma, Huan Yang
The excitation of quadratic quasinormal modes is an important nonlinear phenomenon for a Kerr black hole ringing at a specific linear mode. The amplitude of this second-order effec…
Nonlinear Effects In Black Hole Ringdown From Scattering Experiments I: spin and initial data dependence of quadratic mode coupling
Hengrui Zhu, Justin L. Ripley, Frans Pretorius +13
We investigate quadratic quasinormal mode coupling in black hole spacetime through numerical simulations of single perturbed black holes using both numerical relativity and second-…
