Colliding black holes: analytic insights
Jorge Pullin
TL;DR
This paper reviews the current analytical methods used to understand black hole collisions, focusing on perturbation theory approaches for head-on collisions and prospects for studying non-axisymmetric interactions.
Contribution
It provides a comprehensive summary of first and second order perturbation theory results for black hole collisions and discusses future directions for non-axisymmetric collision analysis.
Findings
Perturbation theory effectively models head-on black hole collisions.
Second order perturbation results improve accuracy over first order.
Future work aims to extend analysis to non-axisymmetric collisions.
Abstract
We summarize the state of the art of the ``close approximation'' to black hole collisions. We discuss results to first and second order in perturbation theory for head-on collisions of momentarily-stationary and non-stationary black holes and discuss the near-future prospect of non-axisymmetric collisions.
