Geometric horizons in binary black hole mergers
Alan Coley, Jeremy M Peters, Erik Schnetter
We numerically study the algebraic properties of the Weyl tensor through the merger of two non-spinning black holes (BHs). We are particularly interested in the conjecture that for…
Geometric Horizons: A Frame Approach
A. A. Coley, D. D. McNutt
In the numerical investigation of the physical merger of two black holes, it is crucial to locate a black hole locally. This is usually done utilizing an apparent horizon. An alter…
Teleparallel geometries not characterized by their scalar polynomial torsion invariants
D. D. McNutt, A. A. Coley, R. J. van den Hoogen
A teleparallel geometry is an n-dimensional manifold equipped with a frame basis and an independent spin connection. For such a geometry, the curvature tensor vanishes and the tors…
Comment on "Szekeres universes with homogeneous scalar fields"
Ismael Delgado Gaspar, Roberto A. Sussman, David D. McNutt +1
Two recently published papers (J.D. Barrow and A. Paliathanasis, Eur. Phys. J. C. (2018, 2019)) claim to have found exact solutions of Einstein's field equations belonging to the c…
An invariant characterization of the quasi-spherical Szekeres dust models
A. A. Coley, N. Layden, D. D. McNutt
The quasi-spherical Szekeres dust solutions are a generalization of the spherically symmetric Lemaitre-Tolman-Bondi dust models where the spherical shells of constant mass are non-…
