Number Counts and Dynamical Vacuum Cosmologies
N. Chandrachani Devi, H. A. Borges, S. Carneiro +1
We study non-linear structure formation in an interacting model of the dark sector of the Universe in which the dark energy density decays linearly with the Hubble parameter, $ρ_Λ…
SNe Ia Tests of Quintessence Tracker Cosmology in an Anisotropic Background
W. Miranda, S. Carneiro, C. Pigozzo
We investigate the observational effects of a quintessence model in an anisotropic spacetime. The anisotropic metric is a non-rotating particular case of a generalized Godel's metr…
Interacting vacuum energy in the dark sector
L. P. Chimento, S. Carneiro
We analyse three cosmological scenarios with interaction in the dark sector, which are particular cases of a general expression for the energy flux from vacuum to matter. In the fi…
J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey
N. Benitez, R. Dupke, M. Moles +149
The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a narrow band, very wide field Cosmological Survey to be carried out from the Javalambre Observat…
On dark degeneracy and interacting models
S. Carneiro, H. A. Borges
Cosmological background observations cannot fix the dark energy equation of state, which is related to a degeneracy in the definition of the dark sector components. Here we show th…
Concordance Cosmology with Particle Creation
Saulo Carneiro
A constant-rate creation of dark particles in the late-time FLRW spacetime provides a cosmological model in accordance with precise observational tests. The matter creation backrea…
