An Integrated Procedure for Tree-Nbody Simulations: FLY and AstroMD
U. Becciani, V. Antonuccio-Delogu, F. Buonomo +1
We present a code allowing to evolve three-dimensional self-gravitating collisionless systems with a large number of particles N >= 10^7. FLY (Fast Level-based N-bodY code) is a fu…
AstroMD. A multi-dimensional data analysis tool for astrophysical simulations
U. Becciani, V. Antonuccio-Delogu, C. Gheller +3
Over the past few years, the role of visualization for scientific purpose has grown up enormously. Astronomy makes an extended use of visualization techniques to analyze data, and…
Structural properties of Dark Matter Halos
V. Antonuccio-Delogu, U. Becciani, A. Pagliaro
Using the results of a high mass resolution ( particles) N-body simulation of a cluster-forming region, we study the statistic for low mass halos (${\rm M} < 10^…
Are Low Surface Brightness Discs Young?
Paolo Padoan, Raul Jimenez, Vincenzo Antonuccio-Delogu
We reconsider the problem of the age of the stellar discs of late-type Low Surface Brightness (LSB) galaxies by making use of a new IMF recently derived from numerical fluid dynami…
Velocity correlation tensor and substructure's statistics around density peaks
V. Antonuccio-delogu, S. Colafrancesco
We derive the conditional probability distribution of the peculiar velocity around a peak of given overdensity in a Gaussian density field. This distribution characterizes the shea…
On the Origin of Low-Surface-Brightness Galaxies
V. Antonuccio-Delogu
We reconsider the problem of the origin of Low-Surface-Brightness (LSB) galaxies within the standard Cold Dark Matter (CDM) cosmological model (). Taking into account t…
