Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

We review applications of string theory to cosmology, from primordial times to the present-
day accelerated expansion. Starting with a brief overview of cosmology and string …

We report on the implications for cosmic inflation of the 2018 release of the Planck cosmic
microwave background (CMB) anisotropy measurements. The results are fully consistent …

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 …

ABSTRACT The Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data provide
stringent limits on deviations from the minimal, six-parameter Λ cold dark matter model. We …

Abstract Euclid is a European Space Agency medium-class mission selected for launch in
2020 within the cosmic vision 2015–2025 program. The main goal of Euclid is to understand …

The past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

Nonlocal primordial non-Gaussianity (NLPNG) is a smoking gun of interactions in single-
field inflationary models and can be written as a combination of the equilateral and …

This is a review of models of inflation and of their predictions for the primordial non-
Gaussianity in the density perturbations which are thought to be at the origin of structures in …

The theory of inflation with single and multiple fields is reviewed paying particular attention
to the dynamics of adiabatic and entropy/isocurvature perturbations which provide the …
