Cosmological perturbations in the Tsallis holographic dark energy scenarios
W. J. C. da Silva, R. Silva
We investigate the Tsallis holographic dark energy (THDE) models in the context of perturbations' growth. We assume the description of dark energy by considering the holographic pr…

Growth of matter perturbations in the extended viscous dark energy models
W. J. C. da Silva, R. Silva
In this work, we study the extended viscous dark energy models in the context of matter perturbations. To do this, we assume an alternative interpretation of the flat Friedmann-Lem…

Extended CDM model and viscous dark energy: A Bayesian analysis
W. J. C. da Silva, R. Silva
We propose an approach considering the nonextensive effects in the context of the Verlinde theory in order to address an extended cosmological model in the context of viscous dark…
