Dynamics Of Scalar Fields Around Black Holes

Juan Carlos Degollado

U. Aveiro

Abstract / Resumo 

Classical scalar fields provide one of the simplest sources of stress-energy in Einstein's equations. Interest in scalar fields has been stimulated in recent years by theoretical developments in particle physics and cosmology. In particular, ultra-light scalar fields have been invoked as possible candidates to play the role of the dark matter component of the universe. Given the fact that most galaxies seem to contain a super-massive black hole at their centres, it is important to study the dynamical properties of the system. In this talk I will revisit some processes involving time-dependent scalar field configurations around black holes, and I will show some recent results.
