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 …

Measurement of the distances to nearby galaxies has improved rapidly in recent decades.
The ever-present challenge is to reduce systematic effects, especially as greater distances …

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 …

We present the cosmological implications from final measurements of clustering using
galaxies, quasars, and Ly α forests from the completed Sloan Digital Sky Survey (SDSS) …

We present new arcminute-resolution maps of the Cosmic Microwave Background
temperature and polarization anisotropy from the Atacama Cosmology Telescope, using …

The difference from 4 to 6 σ in the Hubble constant (H 0) between the values observed with
the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave …

We present a measurement of the Hubble constant (H 0) and other cosmological parameters
from a joint analysis of six gravitationally lensed quasars with measured time delays. All …

We present a new and independent determination of the local value of the Hubble constant
based on a calibration of the tip of the red giant branch (TRGB) applied to Type Ia …
