Superradiant instabilities in astrophysical systems
If you have a question about this talk, please contact Dr Joan Camps.
Black holes are key players in a wide range of fundamental physics including astrophysics as well as high energy physics. Crucial questions concern their stability properties with potentially important implications for the phase-space of solutions or the understanding of condensates in the vicinity of black holes. Of particular interest is the superradiant or “BH-bomb” like instability of Kerr BHs which arises naturally in aymptotically anti-de Sitter spacetimes or in the presence of massive fields surrounding the BH.
Here, we focus on the latter scenario and present our investigations of massive scalar and vector fields in BH backgrounds. Specifically, we have explored the time evolution of these fields with generic initial configurations in highly spinning BH environments. We have found interesting, non-trivial evolution patterns and have been able to deduce the growth rate of the superradiant instability.
