Apparent horizon tracking in supercritical solutions of the Einstein-scalar field equations in spherical symmetry in affine-null coordinates
Thomas Mädler, Olaf Baake, Hamideh Hosseini +1
Choptuik's critical phenomena in general relativity is revisited in the affine-null metric formulation of Einstein's equations for a massless scalar field in spherical symmetry. Nu…
The affine-null formulation of the gravitational equations: spherical case
J. A. Crespo, H. P. de Oliveira, J. Winicour
A new evolution algorithm for the characteristic initial value problem based upon an affine parameter rather than the areal radial coordinate used in the Bondi-Sachs formulation is…
Kerr Black Holes and Nonlinear Radiation Memory
Thomas Mädler, Jeffrey Winicour
The Minkowski background intrinsic to the Kerr-Schild version of the Kerr metric provides a definition of a boosted spinning black hole. There are two Kerr-Schild versions correspo…
Toward computing gravitational initial data without elliptic solvers
István Rácz, Jeffrey Winicour
Two new methods have been proposed for solving the gravitational constraints without using elliptic solvers by formulating them as either an algebraic-hyperbolic or parabolic-hyper…
Boosted Schwarzschild Metrics from a Kerr-Schild Perspective
Thomas Mädler, Jeffrey Winicour
The Kerr-Schild version of the Schwarzschild metric contains a Minkowski background which provides a definition of a boosted black hole. There are two Kerr-Schild versions correspo…
The Algebraic-Hyperbolic Approach to the Linearized Gravitational Constraints on a Minkowski Background
Jeffrey Winicour
An algebraic-hyperbolic method for solving the Hamiltonian and momentum constraints has recently been shown to be well posed for general nonlinear perturbations of the initial data…
