Constraining a possible time-variation of the speed of light along with the fine-structure constant using strong gravitational lensing and Type Ia supernovae observations
L. R. Colaço, S. J. Landau, J. E. Gonzalez +2
The possible time variation of the fundamental constants of nature has been an active subject of research since the large-number hypothesis was proposed by Dirac. In this paper, we…
Physical constraints on interacting dark energy models
J. E. Gonzalez, H. H. B. Silva, R. Silva +1
Physical limits on the equation-of-state (EoS) parameter of a dark energy component non-minimally coupled with the dark matter field are examined in light of the second law of ther…
Smoothing expansion rate data to reconstruct cosmological matter perturbations
J. E. Gonzalez, J. S. Alcaniz, J. C. Carvalho
The existing degeneracy between different dark energy and modified gravity cosmologies at the background level may be broken by analysing quantities at the perturbative level. In t…
Non-parametric reconstruction of cosmological matter perturbations
J. E. Gonzalez, J. S. Alcaniz, J. C. Carvalho
Perturbative quantities, such as the growth rate () and index (), are powerful tools to distinguish different dark energy models or modified gravity theories even if they pro…
