Journal ArticleDOI
Evolution of binary black-hole spacetimes.
Frans Pretorius,Frans Pretorius +1 more
TL;DR: Early success is described in the evolution of binary black-hole spacetimes with a numerical code based on a generalization of harmonic coordinates capable of evolving binary systems for enough time to extract information about the orbit, merger, and gravitational waves emitted during the event.
Journal ArticleDOI
Theoretical physics implications of the binary black-hole mergers GW150914 and GW151226
TL;DR: The recent gravitational wave observations GW150914 and GW151226 reported by the LIGO and Virgo collaborations confirmed a key prediction of general relativity (GR) as discussed by the authors.
Journal ArticleDOI
Fundamental theoretical bias in gravitational wave astrophysics and the parametrized post-Einsteinian framework
Nicolás Yunes,Frans Pretorius +1 more
TL;DR: In this article, a parametrized post-Einsteinian framework is proposed to interpolate between templates constructed in general relativity and well-motivated alternative theories of gravity, and also include extrapolations that follow sound theoretical principles such as consistency with conservation laws and symmetries.
Journal ArticleDOI
Dynamical Chern-Simons modified gravity: Spinning black holes in the slow-rotation approximation
Nicolás Yunes,Frans Pretorius +1 more
TL;DR: In this article, the authors proposed a rotating black hole solution for the low energy limit of string theory, which is axisymmetric and stationary, constituting a deformation of the Kerr metric with dipole scalar hair.
Journal ArticleDOI
Black strings, low viscosity fluids, and violation of cosmic censorship.
TL;DR: In this paper, the behavior of 5-dimensional black strings subject to the Gregory-Laflamme instability is described, where at intermediate stages the horizon can be described as a sequence of 3-dimensional spherical black holes joined by black string segments.
