Spectrum of the linearized Vlasov--Poisson equation around steady states from galactic dynamics
Matias Moreno, Paola Rioseco, Hanne Van Den Bosch
We study the linearized Vlasov-Poisson equation in the gravitational case around steady states that are decreasing and continuous functions of the energy. We identify the absolutel…

Phase space mixing of a Vlasov gas in the exterior of a Kerr black hole
Paola Rioseco, Olivier Sarbach
We study the dynamics of a collisionless kinetic gas whose particles follow future-directed timelike and spatially bound geodesics in the exterior of a sub-extremal Kerr black hole…
