Description
In this work, we discuss black hole formation in general relativity. We aim to study the critical collapse of scalar field data numerically. We are interested in analysing this collapse from the point of view of an observer located “at” infinity, which allows us to extract global properties of the system from Einstein's equations [Pürrer, 2005].
We have already successfully implemented a toy model that we’ll further develop to study the scalar field critical collapse. Later on, we will extend Pürrer’s work by studying the collapse of a Yang-Mills field. Furthermore, we aim to compare the obtained results using a null foliation approach with the results of different approaches to the same physical problem, such as spacelike foliation based on truncated Cauchy slices, as well as a hyperboloidal evolution.
