Unified early and late Universe cosmology through dissipative effects in steep quintessential inflation potential models
Gustavo B. F. Lima, Rudnei O. Ramos
By making use of a class of steep exponential type of potentials, which has been recently used to describe quintessential inflation, we show how a unified picture for both inflatio…
New observational constraints on interacting dark energy using galaxy clusters virial equilibrium states
Morgan Le Delliou, Rafael J. F. Marcondes, Gastão B. Lima Neto
As the dark sector remains unknown in composition and interaction between dark energy and dark matter stand out as natural, observations of galaxy clusters out of equilibrium aboun…
Energy, entropy and mass scaling relations for elliptical galaxies. Towards a physical understanding of their photometric properties
I. Marquez, G. B. Lima Neto, H. Capelato +3
In the present paper, we show that elliptical galaxies (Es) obey a scaling relation between potential energy and mass. Since they are relaxed systems in a post violent-relaxation s…
The rich cluster of galaxies ABCG 85.I. X-ray analysis
V. Pislar, F. Durret, D. Gerbal +2
We present an X-ray analysis of the rich cluster ABCG 85 based on ROSAT PSPC data. By applying an improved wavelet analysis, we show that our view of this cluster is notably change…
