Description

With the release of DESI DR2, dynamical dark energy (DDE) models gained unprecedented attention as model candidates to release the current cosmological tensions. However, majority do not perform well in relaxing the H0 tension compared to some of the other novel theoretical and phenomenological models in the literature, such as the LsCDM model that can be explained by an AdS-to-dS transition in the late times. This work focuses on the data analysis of models that combine the features of DDE models with transition scenarios to potentially address, foremost, the H0 and other cosmological tensions.
