Various pulsar timing array (PTA) experiments (NANOGrav, EPTA, PPTA, CPTA, including
data from InPTA) very recently reported evidence for excess red common-spectrum signals …

We consider the simplest anisotropic generalization, as a correction, to the standard Λ CDM
model, by replacing the spatially flat Robertson-Walker metric by the Bianchi type-I metric …

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 …

We present cosmological constraints from Planck 2015 data for a Universe that is kinetically
dominated at very early times. We perform a Markov chain Monte Carlo analysis to estimate …

We perform a Bayesian model selection analysis for different classes of phenomenological
coupled scenarios of dark matter and dark energy with linear and non-linear interacting …

We make a case for setting initial conditions for inflation at the Planck epoch in the kinetically
dominated regime. For inflationary potentials with a plateau or a hill, ie, potentials that are …

The β-exponential inflation is driven by a class of primordial potentials, derived in the
framework of braneworld scenarios, that generalizes the well-known power law inflation. In …

Context. Several satellite missions have uncovered a series of potential anomalies in the
fluctuation spectrum of the cosmic microwave background temperature, including:(1) an …

We analyze a class of generalized inflationary models proposed in ref.[1], known as β-
exponential inflation. We show that this kind of potential can arise in the context of brane …

The search for alternative cosmological models is largely motivated by the growing
discordance between the predictions of ΛCDM and the ever-improving observations, such …
