The first generation of stars, often called Population III (or Pop III), form from metal-free
primordial gas at redshifts z∼ 30 and below. They dominate the cosmic star-formation …

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 …

We present a sample-variance-limited measurement of the temperature power spectrum
(TT) of the cosmic microwave background using observations of a∼ 1500 deg 2 field made …

Abstract LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation
from cosmic background Radiation Detection, is a space mission for primordial cosmology …

We present cosmological parameter constraints using maps from the last Planck data
release (PR4). In particular, we detail an upgraded version of the cosmic microwave …

We present constraints on the tensor-to-scalar ratio r using a combination of BICEP/Keck
2018 (BK18) and Planck PR4 data allowing us to fit for r consistently with the six parameters …

We present cosmological constraints from a cosmic shear analysis of the fourth data release
of the Kilo-Degree Survey (KiDS-1000), which doubles the survey area with nine-band …

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

We describe the legacy Planck cosmic microwave background (CMB) likelihoods derived
from the 2018 data release. The overall approach is similar in spirit to the one retained for …

Abstract Analysis of the Planck 2018 data set indicates that the statistical properties of the
cosmic microwave background (CMB) temperature anisotropies are in excellent agreement …
