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 review recent trends in inflationary dynamics in the context of viable modified gravity
theories. After providing a general overview of the inflationary paradigm emphasizing on …

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 …

In this paper, we propose a novel mechanism in Bbb T 2-inflation to enhance the power
spectrum large enough to seed primordial black holes (PBHs) formation. To accomplish this …

This article is intended to review the recent developments in the Horndeski theory and its
generalization, which provide us with a systematic understanding of scalar–tensor theories …

Reference Design, and Project Plan CMB-S4 Collaboration July 9, 2019 arXiv:1907.04473v1 …

We present a detailed exposition on the prospects of the formation of Primordial Black Holes
(PBHs) during Slow Roll (SR) to Ultra Slow Roll (USR) sharp transitions in the framework of …

This white paper summarizes recent progress in the cosmological bootstrap, an approach to
the study of the statistics of primordial fluctuations from consistency with unitarity, locality and …

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 review presents a comprehensive overview of galaxy bias, that is, the statistical relation
between the distribution of galaxies and matter. We focus on large scales where cosmic …
