Trapping, Irregular Waveforms, and Efficient Radiation in Ultra-relativistic Black Hole Encounters
Hengrui Zhu, Frans Pretorius, James M. Stone
We demonstrate that ultra-relativistic black hole encounters reveal a new regime of the two-body interaction in general relativity. Evolving equal-mass, nonspinning black holes wit…
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…
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-…
