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 …

The isotropy and homogeneity of the cosmic microwave background (CMB) favors “scalar
driven” early Universe inflationary models. However, gauge fields and other non-scalar …

The current flow of high accuracy astrophysical data, among which are the Cosmic
Microwave Background (CMB) measurements by the Planck satellite, offers an …

The Ooguri-Vafa swampland conjectures claim that in any consistent theory of quantum
gravity, when venturing to large distances in scalar field space, a tower of particles will …

We explicitly construct a double-field inflationary model, which satisfies the latest Planck
constraints at the cosmic microwave background (CMB) scales and produces the whole dark …

A bstract Models of large-field inflation based on axion-like fields with shift symmetries can
be simple and natural, and make a promising prediction of detectable primordial …

We analyze string-theoretic large-field inflation in the regime of spontaneously-broken
supergravity with conventional moduli stabilization by fluxes and non-perturbative effects …

A bstract We present strong evidence that the tree level slow roll bounds of arXiv:
1807.05193 and arXiv: 1810.05506 are valid, even when the tachyon has overlap with the …

The standard cosmological model is in the midst of a stress test, thanks to the tension
between supernova-based measurements of the Hubble constant H 0 and inferences of its …

The difficulty of building metastable vacua in string theory, has led some to conjecture that in
the string theory landscape, potentials satisfy|∇ V/V|≥ c∼ O (1). This condition, which is …
