Can Two Ultrarelativistic Objects Lose Almost All Their Energy to Gravitational Radiation?
Don N. Page
In 2007 Pretorius and Khurana did "speculate that at threshold [at a critical impact parameter], all of the kinetic energy of the system [two ultrarelativistic black holes] is conv…
Critical Gravitational Inspiral of Two Massless Particles
Don N. Page
If two ultrarelativistic nonrotating black holes of masses and approach each other with fixed center-of-momentum (COM) total energy that…
Photon Boomerang in a Nearly Extreme Kerr Metric
Don N. Page
The Kerr rotating black hole metric has unstable photon orbits that orbit around the hole at fixed values of the Boyer-Lindquist coordinate that depend on the axial angular mom…
No Violation of the Second Law in Extended Black Hole Thermodynamics
Shi-Qian Hu, Yen Chin Ong, Don N. Page
Recently a number of papers have claimed that the horizon area - and thus the entropy - of near extremal black holes in anti-de Sitter spacetimes can be reduced by dropping particl…
Scalar Polynomial Curvature Invariant Vanishing on the Event Horizon of Any Black Hole Metric Conformal to a Static Spherical Metric
David D. McNutt, Don N. Page
We construct a scalar polynomial curvature invariant that transforms covariantly under a conformal transformation from any spherically symmetric metric. This invariant has the addi…
A New Way to Derive the Taub-NUT Metric with Positive Cosmological Constant
Kento Osuga, Don N. Page
We investigate a biaxial Bianchi IX model with positive cosmological constant, which is sometimes called the Lambda-Taub-NUT spacetime, whose exact solution is well known. The mini…
