Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

The recent results on the baryon acoustic oscillations measurements from the DESI
collaboration have shown tantalizing hints for a time-evolving dark energy equation of state …

We investigate in detail a family of quintessential inflation models in the context of R+ R 2
Palatini modified gravity. We find that successful inflation and quintessence are obtained …

In this article we calculate the reheating temperature in the cosmological scenarios where
heavy scalar particles are gravitationally produced, due to a conformally coupled interaction …

Due to universality and attractor properties, α-attractor quintessential inflation establishes
direct relations between inflationary observables such as the scalar tilt ns and the tensor-to …

The equations for quintessential α-attractor inflation with a single scalar field, radiation and
matter in a spatially flat FLRW spacetime are recast into a regular dynamical system on a …

A unified multiscalar field model with three flat regions is discussed. The three flat regions
are the inflation, early-and late dark energy epochs. The potential is obtained by a …

Quintessential inflation refers to scenarios in which a single scalar field is used to describe
inflation and late time acceleration. This review is dedicated to the framework of …

Recently a new kind of quintessential inflation coming from the Lorentzian distribution has
been introduced in [1, 2]. The model leads to a very simple potential, which basically …
