On Toroidal Horizons in Binary Black Hole Inspirals
Michael I. Cohen, Jeffrey D. Kaplan, Mark A. Scheel
We examine the structure of the event horizon for numerical simulations of two black holes that begin in a quasicircular orbit, inspiral, and finally merge. We find that the spatia…
Horizon dynamics of distorted rotating black holes
Tony Chu, Harald P. Pfeiffer, Michael I. Cohen
We present numerical simulations of a Kerr black hole perturbed by a pulse of ingoing gravitational radiation. For strong perturbations we find up to five concentric marginally out…
Searches for Cosmic-String Gravitational-Wave Bursts in Mock LISA Data
Michael I. Cohen, Curt Cutler, Michele Vallisneri
A network of observable, macroscopic cosmic (super-)strings may have formed in the early universe. If so, the cusps that generically develop on cosmic-string loops emit bursts of g…
Momentum flow in black-hole binaries: II. Numerical simulations of equal-mass, head-on mergers with antiparallel spins
Geoffrey Lovelace, Yanbei Chen, Michael Cohen +6
Research on extracting science from binary-black-hole (BBH) simulations has often adopted a "scattering matrix" perspective: given the binary's initial parameters, what are the fin…
Revisiting Event Horizon Finders
Michael I. Cohen, Harald P. Pfeiffer, Mark A. Scheel
Event horizons are the defining physical features of black hole spacetimes, and are of considerable interest in studying black hole dynamics. Here, we reconsider three techniques t…
