Quantum Mechanics of the Interior of Radiating 2-D Black Holes
Jack Gegenberg, Gabor Kunstatter, Timothy Taves
We study the homogeneous sector of the RST model describing the gravitational dynamics, including back-reaction, of radiating 2-d black holes. We find the exact solutions both in c…
Hamiltonian Formulation of Scalar Field Collapse in Einstein Gauss Bonnet Gravity
T. Taves, C. D. Leonard, G. Kunstatter +1
We compute the Hamiltonian for spherically symmetric scalar field collapse in Einstein-Gauss-Bonnet gravity in D dimensions using slicings that are regular across future horizons.…
Highly Damped Quasinormal Modes and the Small Scale Structure of Quantum Corrected Black Hole Exteriors
James Babb, Ramin G. Daghigh, Gabor Kunstatter
Quasinormal modes provide valuable information about the structure of spacetime outside a black hole. There is also a conjectured relationship between the highly damped quasinormal…
Gravitational collapse of K-essence Matter in Painlevé-Gullstrand coordinates
C. Danielle Leonard, Jonathan Ziprick, Gabor Kunstatter +1
We conduct numerical simulations in Painlevé-Gullstrand coordinates of a variety of K-essence-type scalar fields under spherically symmetric gravitational collapse. We write down g…
Higher Dimensional Choptuik Scaling in Painleve Gullstrand Coordinates
Tim Taves, Gabor Kunstatter
We investigate Choptuik scaling in the spherically symmetric collapse of a massless scalar field in higher dimensions using Painleve-Gullstrand (P-G) coordinates. Our analysis conf…
Dynamical Surface Gravity in Spherically Symmetric Black Hole Formation
Mathias Pielahn, Gabor Kunstatter, Alex B. Nielsen
We study dynamical surface gravity in a general spherically symmetric setting using Painlevé-Gullstrand (PG) coordinates. Our analysis includes several definitions that have been p…
