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-…
Fixing the BMS frame of numerical relativity waveforms with BMS charges
Keefe Mitman, Leo C. Stein, Michael Boyle +8
The Bondi-van der Burg-Metzner-Sachs (BMS) group, which uniquely describes the symmetries of asymptotic infinity and therefore of the gravitational waves that propagate there, has…
Black Hole Formation in AdS Einstein-Gauss-Bonnet Gravity
Nils Deppe, Allison Kolly, Andrew R. Frey +1
AdS spacetime has been shown numerically to be unstable against a large class of arbitrarily small perturbations. In arXiv:1410.1869, the authors presented a preliminary study of t…
Stability of AdS in Einstein Gauss Bonnet Gravity
Nils Deppe, Allison Kolly, Andrew Frey +1
Recently it has been argued that in Einstein gravity Anti-de Sitter spacetime is unstable against the formation of black holes for a large class of arbitrarily small perturbations.…
