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 …

A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

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 …

Despite the remarkable success of the Λ Cold Dark Matter (Λ CDM) cosmological model, a
growing discrepancy has emerged (currently measured at the level of∼ 4− 6 σ) between the …

The current cosmological probes have provided a fantastic confirmation of the standard Λ
Cold Dark Matter cosmological model, which has been constrained with unprecedented …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

Phantom dark energy (w<-1) can produce amplified cosmic acceleration at late times, thus
increasing the value of H 0 favored by CMB data and releasing the tension with local …

We combine 23 Hubble constant measurements based on Cepheids-SN Ia, TRGB-SN Ia,
Miras-SN Ia, Masers, Tully Fisher, Surface Brightness Fluctuations, SN II, Time-delay …

The Hubble constant tension problem is analyzed in the framework of a class of modified
gravity, the so-called F (R) gravity. To do so, we explore two models: an exponential and a …

In this work, we study different types of dark energy (DE) models in the framework of the
cosmographic approach, with emphasis on the running vacuum models (RVMs). We assess …
