Penrose's singularity theorem and the Kerr space-time
Jonathan Brook, Chris Stevens
In this short paper, Penrose's famous singularity theorem is applied to the Kerr space-time. In the case of the maximally extended space-time, the assumptions of Penrose's singular…

Axion-Photon Conversion Signals from Neutron Stars with Spacetime Curvature Accounted for in the Magnetosphere Model
Jesse Satherley, Chris Gordon, Chris Stevens
Axions are a well-motivated dark matter candidate. They may be detectable from radio line emission due to resonant conversion in neutron star magnetospheres. While radio data colle…

First investigation of void statistics in numerical relativity simulations
Michael J. Williams, Hayley J. Macpherson, David L. Wiltshire +1
We apply and extend standard tools for void statistics to cosmological simulations that solve Einstein's equations with numerical relativity (NR). We obtain a simulated void catalo…
