Current constraints on the minimally extended varying speed of light model through the cosmic distance duality relation
Jaiane Santos, Carlos Bengaly, Rodrigo S. Gonçalves
One of the most crucial tests of the standard cosmological model consists on testing possible variations on fundamental physical constants. In frameworks such as the minimally exte…

Non-parametric reconstructions of cosmic curvature: current constraints and forecasts
Mariana L. S. Dias, Antônio F. B. da Cunha, Carlos A. P. Bengaly +2
The assumption of a flat Universe that follows the cosmological principle, i.e., that the universe is statistically homogeneous and isotropic at large scales, comprises one of the…

Measuring the speed of light with cosmological observations: current constraints and forecasts
Jaiane Santos, Carlos Bengaly, Jonathan Morais +1
We measure the speed of light with current observations, such as Type Ia Supernova, galaxy ages, radial BAO mode, as well as simulations of forthcoming redshift surveys and gravita…
