Black-hole threshold solutions in stiff fluid collapse
Patrick R. Brady, Matthew W. Choptuik, Carsten Gundlach +1
Numerical studies of the gravitational collapse of a stiff (P=rho) fluid have found the now familiar critical phenomena, namely scaling of the black hole mass with a critical expon…
Covariant double-null dynamics: -splitting of the Einstein equations
P. R. Brady, S. Droz, W. Israel +1
The paper develops a -imbedding formalism adapted to a double foliation of spacetime by a net of two intersecting families of lightlike hypersurfaces. The formalism is two-d…
Non-linear instability of Kerr-type Cauchy horizons
Patrick R Brady, Chris M Chambers
Using the general solution to the Einstein equations on intersecting null surfaces developed by Hayward, we investigate the non-linear instability of the Cauchy horizon inside a re…
Cauchy horizon singularity without mass inflation
P. R. Brady, D. Nunez, S. Sinha
A perturbed Reissner-Nordström-de Sitter solution is used to emphasize the nature of the singularity along the Cauchy horizon of a charged spherically symmetric black hole. For the…
Vacuum Polarisation and the Black Hole Singularity
W. G. Anderson, P. R. Brady, R. Camporesi
In order to investigate the effects of vacuum polarisation on mass inflation singularities, we study a simple toy model of a charged black hole with cross flowing radial null dust…
Quantum Effects in Black Hole Interiors
Warren G. Anderson, Patrick R. Brady, Werner Israel +1
The Weyl curvature inside a black hole formed in a generic collapse grows, classically without bound, near to the inner horizon, due to partial absorption and blueshifting of the r…
