Reconstructing the cosmic expansion with a generalized q(z) parameterization: A decelerating Universe from late-time constraints
Tomás Verdugo, Alberto Hernández-Almada, Miguel A. GarcÃa-Aspeitia +2
We present a generalized phenomenological parameterization of the deceleration parameter that incorporates an effective radiative component (ERC) in addition to a localized…

Constraints on Tsallis cosmology using recent low and high redshift measurements
M. L. Mendoza-MartÃnez, A. Cervantes-Contreras, J. J. Trejo-Alonso +1
Recently Tsallis cosmology has been presented as a novel proposal for alleviating both and tensions. Hence a universe filled with matter and radiation as perfect fluid…
