The group's research on strong gravity involves finding analytical and numerical solutions of Einstein's theory of general relativity, and many of its extensions, either in vacuum or coupled to various types of matter. For our latest developments/activities in this area, please see the listing at the end of this article.
The prime examples of (relativistic) strong gravitational systems are Black Holes. They are truly unifying objects of all physics. The understanding of their formation and dynamics requires the laws of all four fundamental forces, and their physics is relevant not only for astrophysics and cosmology but for a variety of topics within high energy physics.
See here a movie made by the COST action `Black holes in a violent universe', in which our group participates, for a visual overview of different types of black holes.
A plausible model of inflation driven by strong gravitational wave turbulence

Abstract: TBD
Black holes are the most massive objects in the Universe and provide an ideal testing ground for gravity in the strong field regime.
The NewFunFiCO mid term meeting took place online on March 20 bringing together many consortium members, to share their experiences with the REA.
