Cosmic Censorship: A study of the behavior of regular black holes
… that all singularities must be hidden behind the event horizon. Consequently, this conjecture forbids the destruction of event horizons in singular black holes, since their removal would expose naked singularities. Regular black holes, by contrast, contain no curvature singularities and are …

Rotating black hole spacetimes
… a study of their evolutions including apparent horizons, event horizons and gravitational radiation, is presented. These initial data sets represent distorted rotating black holes, and two types of non-rotating black holes with odd-parity radiation distortions. The first has the equatorial plane …

Approaching the Singularity in Gowdy Universes
… known that in the case of cylindrical symmetry, event horizons will not form under gravitational collapse, so the formation of a singularity on the symmetry axis would be a violation of the cosmic censorship conjecture.To search for cosmic censorship violation in Gowdy spacetimes, we must have a …

A Philosophical Re-evaluation of the Problem of Evil: Framing an Embedded Analytic Approach
… and describe their multi-layered consequences as event horizons, using a concept borrowed from astrophysics. I redefine moral evil as the predation of one person upon another and argue that instead of the choice between good and evil humans face a tripartite choice among good, bad and evil. My …

From Quantum Information to Cosmic Censorship: Emergent Spacetimes and Their Surfaces
… matter. Finally, we show a connection between event horizons and CFT pseudorandomness, and we construct a new measure of the size of a naked singularity. We conjecture that quantum gravity only forbids macroscopic naked singularities, according to this measure. In the second part, we derive new …

Perturbations and symmetry in gravitational theories : wormholes, wave dynamics, and quantum effects in rotating spacetimes.
… across gravitational systems without reliance on event horizons.

Horizons, hyperbolic systems, and inner boundary conditions in numerical relativity
… We discuss finding and understanding the event horizon (EH), which is the causal boundary separating the black hole interior from its exterior, in dynamical black hole spacetimes. In the EH studies, we formulate a set of tools for analyzing the behavior of the EH, including proposing a …

General relativistic radiation magnetohydrodynamics, with applications to black hole accretion disks
… lion's share of this internal energy through the event horizon. At near-Eddington accretion rates, advection may be safely ignored, as energy generated from viscous heating is quickly radiated away. What, then, of intermediate accretion rates for which advection, heating, and radiative cooling …
