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 …

Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only
galaxy whose formation history can be studied using the full distribution of stars from faint …

Context. Gaia Early Data Release 3 (Gaia EDR3) contains results for 1.812 billion sources in
the magnitude range G= 3–21 based on observations collected by the European Space …

This paper presents the Planck 2015 likelihoods, statistical descriptions of the 2-point
correlationfunctions of the cosmic microwave background (CMB) temperature and …

We present the final nine-year maps and basic results from the Wilkinson Microwave
Anisotropy Probe (WMAP) mission. The full nine-year analysis of the time-ordered data …

A bstract We study the system of axion strings that forms in the early Universe if the Peccei-
Quinn symmetry is restored after inflation. Using numerical simulations, we establish the …

Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of
General Relativity at infrared and ultraviolet scales. They are an approach that, by …

This paper presents cosmological results based on full-mission Planck observations of
temperature and polarization anisotropies of the cosmic microwave background (CMB) …

Despite having the somewhat successful description of accelerated cosmology, the early
evolution of the universe always challenges mankind. Our promising approach lies in a new …

ABSTRACT WMAP precision data enable accurate testing of cosmological models. We find
that the emerging standard model of cosmology, a flat Λ-dominated universe seeded by a …
