We review the particle theory origin of inflation and curvaton mechanisms for generating
large scale structures and the observed temperature anisotropy in the cosmic microwave …

We critically review the role of cosmological moduli in determining the post-inflationary
history of the universe. Moduli are ubiquitous in string and M-theory constructions of beyond …

We investigate the two-stage inflation regime in the theory of hybrid cosmological α-
attractors. The spectrum of inflationary perturbations is compatible with the latest …

Primordial black holes (PBHs) generated by gravitational collapse of large primordial
overdensities can be a fraction of the observed dark matter. In this paper, we introduce a …

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

Within the framework of scalar-tensor theories, we study the conditions that allow single field
inflation dynamics on small cosmological scales to significantly differ from that of the large …

We compute the rate with which super-Hubble cosmological fluctuations are decohered
during inflation, by their gravitational interactions with unobserved shorter-wavelength scalar …

We develop a formalism to characterize the shape and the redshift evolution of the dark
energy potential. Our formalism makes use of quantities similar to the horizon-flow …

Cosmological α-attractors stand out as particularly compelling models to describe inflation in
the very early universe, naturally meeting tight observational bounds from cosmic microwave …

We compute the Bayesian evidence and complexity of 193 slow-roll single-field models of
inflation using the Planck 2013 Cosmic Microwave Background data, with the aim of …
