On an empirical method to build near-equilibrium axisymmetric and triaxial galaxy models
Pierfrancesco Di Cintio, Alessandro Alberto Trani, Valentina Cesare
We introduce a numerical technique to implement body realizations of axisymmetric and triaxial self-gravitating system starting from a spherical self-consistent models for whic…
The stability of radially anisotropic rotating stellar systems with a central density cusp
Pierfrancesco Di Cintio, Anna Lisa Varri
We investigate the interplay between radial velocity anisotropy and internal rotation in self-gravitating systems characterised by initial spherical symmetry and a moderate density…
Beyond the Largest Lyapunov Exponent: Entropy-Based Diagnostics of Chaos in Henon-Heiles and N-Body Dynamics
Alessandro Alberto Trani, Pierfrancesco Di Cintio, Michele Ginolfi
The largest Lyapunov exponent is widely used to diagnose chaos in gravitational dynamics, but in mixed phase spaces and finite-N systems it does not always provide a complete descr…
Generalized flux-weighted boundary walls in kinetic models
Luca Barbieri, Pierfrancesco Di Cintio
We present a technique to investigate the stationary states of a system of a collisionless system confined by an external potential and coupled to boundary reservoirs through presc…
Turbulent drag on stellar mass black holes embedded in disks of active galactic nuclei
Alessandro Alberto Trani, Pierfrancesco Di Cintio
We investigate how AGN disk turbulence affects the orbital dynamics of a stellar-mass black hole (BH) initially located at a migration trap, focusing on the long-term behavior of e…
GW emission and relativistic dynamical friction in intermediate mass ratio inspirals
P. Di Cintio, G. Bertone, C. Chiari +4
We present a set of preliminary simulations of intermediate mass ratio inspirals (IMRIs) inside dark matter (DM) spikes accounting for post-Newtonian corrections the interaction be…
