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…
Phase space mixing in an external gravitational central potential
Paola Rioseco, Olivier Sarbach
This article is devoted to the study of the dynamical behavior of a collisionless kinetic gas in d=1,2,3 space dimensions which is trapped in a rotationally symmetric potential wel…
Phase space mixing in the equatorial plane of a Kerr black hole
Paola Rioseco, Olivier Sarbach
It is shown that a collisionless, relativistic kinetic gas configuration propagating in the equatorial plane of a Kerr black hole undergoes a relaxation process and eventually sett…
Spherical steady-state accretion of a relativistic collisionless gas into a Schwarzschild black hole
Paola Rioseco, Olivier Sarbach
In previous work, we derived the most general solution of the collisionless Boltzmann equation describing the accretion of a kinetic gas into a Schwarzschild black hole background,…
Accretion of a relativistic, collisionless kinetic gas into a Schwarzschild black hole
Paola Rioseco, Olivier Sarbach
We provide a systematic study for the accretion of a collisionless, relativistic kinetic gas into a nonrotating black hole. To this end, we first solve the relativistic Liouville e…
Black Hole Solutions for Scale Dependent Couplings: The de Sitter and the Reissner-Nordström Case
Benjamin Koch, Paola Rioseco
Allowing for scale dependence of the gravitational couplings leads to a generalization of the corresponding field equations. In this work, those equations are solved for the Einste…
