Reconstructing the cosmic expansion with a generalized q(z) parameterization: A decelerating Universe from late-time constraints

Tomás Verdugo, Alberto Hernández-Almada, Miguel A. García-Aspeitia +2

We present a generalized phenomenological parameterization of the deceleration parameter $q (z)$ that incorporates an effective radiative component (ERC) in addition to a localized…
