Impulsive mixing of stellar populations in dwarf spheroidal galaxies
Raphaël Errani, Matthew G. Walker, Simon Rozier +2
We study the response of mono-energetic stellar populations with initially isotropic kinematics to impulsive and adiabatic changes to an underlying dark matter potential. Half-ligh…

Forming off-center massive black hole binaries in dwarf galaxies through Jacobi capture
Thibaut L. François, Christian M. Boily, Jonathan Freundlich +2
It is well established that black holes reside in the central regions of virtually all types of known galaxies. Recent observational and numerical studies however challenge this pi…

Collisionless relaxation from near equilibrium configurations: Linear theory and application to tidal stripping
Simon Rozier, Raphaël Errani
Placed slightly out of dynamical equilibrium, an isolated stellar system quickly returns towards a steady virialized state. We study this process of collisionless relaxation using…
