TLDR
The masses of the black holes are able to compute the masses from the measurements of their apparent horizons, as well as the total energy radiated and find their sum to be in excellent agreement with the ADM mass.Abstract:
We have developed a numerical code to study the evolution of distorted, rotating black holes. This code is used to evolve a new family of black hole initial data sets corresponding to distorted ``Kerr'' holes with a wide range of rotation parameters, and distorted Schwarzschild black holes with odd-parity radiation. Rotating black holes with rotation parameters as high as $a/m=0.87$ are evolved and analyzed in this paper. The evolutions are generally carried out to about $t=100M$, where $M$ is the ADM mass. We have extracted both the even- and odd-parity gravitational waveforms, and find the quasinormal modes of the holes to be excited in all cases. We also track the apparent horizons of the black holes, and find them to be a useful tool for interpreting the numerical results. We are able to compute the masses of the black holes from the measurements of their apparent horizons, as well as the total energy radiated and find their sum to be in excellent agreement with the ADM mass.read more

Initial Data for Numerical Relativity
TL;DR: This work examines several of the formalisms used for specifying Cauchy initial data in the 3 + 1 decomposition of Einstein’s equations and explores how these formalisms have been used in constructing initial data for spacetimes containing black holes and neutron stars.

TL;DR: In this article, a conformal traceless formulation of the Einstein equations is presented for the study of the gravitational collapse of uniformly rotating neutron stars to Kerr black holes, where the initial stellar models are modeled as relativistic polytropes with angular velocities ranging from slow rotation to the mass shedding limit.

TL;DR: In this article, the authors describe a test of the hypothesis that observations of damped, sinusoidal gravitational waves originate from a black hole or that nature respects the general relativistic no-hair theorem.
