Non-Parametric Analysis for the Dark Matter Density Evolution
Z. C. Santana, R. F. L. Holanda, R. Silva
In this paper, we investigate a potential departure in the standard dark matter density evolution law, . The method involves considering a deformed evolut…
Revisiting Witten-O'Raifeartaigh Inflation for a Non-minimally Coupled Scalar Field
F. B. M. dos Santos, R. Silva
In this work, we revisit the Witten-O'Raifeartaigh model of inflation, in which the potential takes a form, when the scalar field is non-minimally coupl…
Observational Constraints on Gravity from Model-Independent Data
F. B. M. dos Santos, J. E. Gonzalez, R. Silva
We establish new constraints on gravity models by using cosmological data. In particular, we investigate the restrictions given by the gas mass fraction measurements of gala…
Bayesian Comparison of the Cosmic Duality Scenarios
W. J. C. da Silva, R. F. L. Holanda, R. Silva
The cosmic distance duality relation (CDDR), , with and , being the luminosity and angular diameter distances, respectivel…
Probing variation of the fine-structure constant in runaway dilaton models using Strong Gravitational Lensing and Type Ia Supernovae
L. R. Colaço, R. F. L. Holanda, R. Silva
In order to probe a possible time variation of the fine-structure constant (), we propose a new method based on Strong Gravitational Lensing and Type Ia Supernovae observations.…
Investigating the signatures of long-range persistence in seismic sequences along Circum-Pacific subduction zones
D. B. de Freitas, G. S. França, T. Scheerer +2
In the present paper, we analyze the signatures of long-range persistence in seismic sequences along Circum-Pacific subduction zones, from Chile to Kermadec, extracted from the Nat…
