All cosmological observations to date are consistent with adiabatic, Gaussian and nearly
scale invariant initial conditions. These findings provide strong evidence for a particular …

We present the implications for cosmic inflation of the Planck measurements of the cosmic
microwave background (CMB) anisotropies in both temperature and polarization based on …

Cosmic inflation provides a window to the highest energy densities accessible in nature, far
beyond those achievable in any realistic terrestrial experiment. Theoretical insights into the …

We analyse the implications of the Planck data for cosmic inflation. The Planck nominal
mission temperature anisotropy measurements, combined with the WMAP large-angle …

We present the current accounting of systematic effect uncertainties for the Low Frequency
Instrument (LFI) that are relevant to the 2015 release of the Planck cosmological results …

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

The next generation of cosmic microwave background, gravitational wave, and large scale
structure, experiments will provide an unprecedented opportunity to probe the primordial …

In the early universe, energy stored in small-scale density perturbations is quickly dissipated
by Silk damping, a process that inevitably generates μ-and y-type spectral distortions of the …

ABSTRACT The Data Release 4 of the Atacama Cosmology Telescope (ACT) shows an
agreement with an Harrison-Zel'dovich primordial spectrum (ns= 1.009±0.015), introducing …

A bstract If a light axion is present during inflation and becomes part of dark matter
afterwards, its quantum fluctuations contribute to dark matter isocurvature. In this article, we …
