Distorted black hole initial data using the puncture method

PHYSICAL REVIEW D, 70(12).

By: J. Brown n  & L. Lowe n

topics (OpenAlex): Black Holes and Theoretical Physics; Astrophysical Phenomena and Observations; Pulsars and Gravitational Waves Research
TL;DR: This work solves for single distorted black hole initial data using the puncture method, where the Hamiltonian constraint is written as an elliptic equation in R{sup 3} for the nonsingular part of the metric conformal factor. (via Semantic Scholar)
