Tue 1 Apr 2025   14:00 - 15:00	Seminar: GAnG seminar - Betti Hartmann, Black holes and boson stars with wavy scalar hair  Centre for Geometry, Analysis and Gravitation Black holes and boson stars with wavy scalar hair Static, spherically symmetric black holes can carry scalar hair when coupling standard Einstein gravity minimally to a self-interacting complex scalar field and a U(1) gauge field. For this scalar hair to exist, the frequency of the scalar field needs to be fine-tuned. In this talk, I will discuss these solutions and point out that for sufficiently large gravitational coupling, the space-time splits into two distinct parts: (a) an inflating...
