Energy Ranking Preservation in a N-Body Cosmological Simulation
Christine C. Dantas, Fernando M. Ramos
In this paper we present a study of the cosmic flow from the point of view of how clusterings at different dynamical regimes in an expanding universe evolve according to a `coarse-…
Gravitational Mesoscopic Constraints in Cosmological Dark Matter Halos
Christine C. Dantas, Fernando M. Ramos
We present an analysis of the behaviour of the `coarse-grained' (`mesoscopic') rank partitioning of the mean energy of collections of particles composing virialized dark matter hal…
"Fundamental-Plane"-Like Relations From Collisionless Stellar Dynamics: A Comparison of Mergers and Collapses
Christine C. Dantas, Hugo V. Capelato, Andre L. B. Ribeiro +1
We present a new set of dissipationless N-body simulations aiming to better understand the pure dynamical aspects of the ``Fundamental Plane'' (FP) of elliptical galaxies. We have…
Dissipationless Collapse of Spherical Protogalaxies and the Fundamental Plane
Christine C. Dantas, Hugo V. Capelato, Reinaldo R. de Carvalho +1
Following on from the numerical work of Capelato, de Carvalho & Carlberg (1995, 1997), where dissipationless merger simulations were shown to reproduce the "Fundamental Plane" (FP)…
The Two-Component Virial Theorem and the Physical Properties of Stellar Systems
Christine C. Dantas, Andre L. B. Ribeiro, Hugo V. Capelato +1
Motivated by present indirect evidences that galaxies are surrounded by dark matter halos, we investigate whether their physical properties can be described by a formulation of the…
Evidence of Substructure in the Cluster of Galaxies A3558
Christine C. Dantas, Reinaldo R. de Carvalho, Hugo V. Capelato +1
We investigate the dynamical properties of the cluster of galaxies A3558 (Shapley 8). Studying a region of one square degree ( 3 Mpc) centered on the cluster cD galaxy, w…
