The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

We formulate Barrow holographic dark energy, by applying the usual holographic principle
at a cosmological framework, but using the Barrow entropy instead of the standard …

Abstract The Nobel Prize winning confirmation in 1998 of the accelerated expansion of our
Universe put into sharp focus the need of a consistent theoretical model to explain the origin …

Abstract Models where dark matter and dark energy interact with each other have been
proposed to solve the coincidence problem. We review the motivations underlying the need …

We review the paradigm of holographic dark energy (HDE), which arises from a theoretical
attempt of applying the holographic principle (HP) to the dark energy (DE) problem. Making …

We review different dark energy cosmologies. In particular, we present the Λ CDM
cosmology, Little Rip and Pseudo-Rip universes, the phantom and quintessence …

We use observational data from Supernovae (SNIa) Pantheon sample, as well as from direct
measurements of the Hubble parameter from the cosmic chronometers (CC) sample, in …

We construct a holographic dark energy scenario based on Kaniadakis entropy, which is a
generalization of Boltzmann-Gibbs entropy that arises from relativistic statistical theory and …

We investigate interacting scenarios that belong to a wider class, since they include a
dynamical dark energy component whose equation of state follows various one-parameter …
