Parallelization of a Code for the Simulation of Self-gravitating Systems in Astrophysics. Preliminary Speed-up Results
R. Capuzzo-Dolcetta, P. Miocchi
We have preliminary results on the parallelization of a Tree-Code for evaluating gravitational forces in N-body astrophysical systems. For our Cray T3D/CRAFT implementation, we hav…

Galactic Nuclei Activity Sustained by Globular Cluster Mass Accretion
R. Capuzzo-Dolcetta, P. Miocchi
The decay of globular clusters to the center of their mother galaxy corresponds to carrying a quantity of mass sufficient to sustain the gravitational activity of a small pre-exist…

Force Evaluation in Particle Methods for Self-Gravitating Multi-Phase Systems
R. Capuzzo-Dolcetta, R. Di Lisio, P. Miocchi
A modern approach to the evolution of a mixed (stars and gas) self-gravitating system is the fully Lagrangian particle approach. The gaseous (particle) phase differs from the compa…
