Energy equipartition in Globular Clusters through the eyes of dynamical models
M. Teodori, O. Straniero, M. Merafina
Gravitational encounters drive globular clusters toward energy equipartition, mass segregation and evaporation altering structural, spatial and kinematic features. We determine the…
Generalization of the Fokker-Planck equation for stellar orbit diffusion in multi-mass star systems
Marco Merafina, Matteo Teodori
We improve the standard theory of collisional stellar systems by considering the presence of a continuous mass distribution. The calculus of the diffusion coefficients is generaliz…
On self-gravitating strange dark matter halos around galaxies
Marco Merafina, Francesco G. Saturni, Catalina Curceanu +2
A new family of nonrelativistic, Newtonian, non-quantum equilibrium configurations describing galactic halos is introduced, by considering strange quark matter conglomerates with m…
Massive black holes interactions during the assembly of heavy sub-structures in the centre of galaxy clusters
M. Donnari, M. Arca-Sedda, M. Merafina
We performed a series of direct N-body simulations with the aim to follow the dynamical evolution of a galaxy cluster (GC) () in different environ…
The local effect of Dark Energy in galaxy clusters
Martina Donnari, Marco Merafina, Manuel Arca-Sedda
Recently, observational data and high precision mapping of the local velocity field of Local Group and Virgo cluster have revealed a linear velocity-distance relation of the outerm…
Self-Gravitating Relativistic Models of Fermions with Anisotropy and Cutoff Energy in their Distribution Function
Marco Merafina, Giuseppe Alberti
In this paper we study the equilibrium configurations of anisotropic self-gravitating fermions, by extending to general relativity the solutions obtained in a previous paper. This…
