No-scale supergravity realization of the Starobinsky model of inflation.
TL;DR: A model for cosmological inflation based on a no-scale supergravity sector with an SU(2,1)/SU(2)×U(1) Kähler potential, a single modulus T, and an inflaton superfield Φ described by a Wess-Zumino model with superpotential parameters (μ, λ).

Particle physics models of inflation and curvaton scenarios
TL;DR: In this paper, the particle theory origin of inflation and curvaton mechanisms for generating large scale structures and the observed temperature anisotropy in the cosmic microwave background (CMB) radiation are reviewed.

TL;DR: In this article, the Starobinsky R+R2 model was extended to the SU(2,1)/SU(2) × U(1) case, in which the inflaton may be identified with either a modulus field or a matter field.

TL;DR: In this article, the Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data were used to constrain the physics of cosmic inflation via Gaussianity, adiabaticity, the power spectrum of primordial fluctuations, gravitational waves, and spatial curvature.

TL;DR: In this paper, the authors show that the tensor-to-scalar ratio r 1 is disfavored regardless of r. They provide a set of "WMAP distance priors, to test a variety of dark energy models.

TL;DR: This textbook is the first to provide a modern and unified overview of inflationary cosmology and carefully compares predictions with the latest observations, including those of the cosmic microwave background, the clustering and velocities of galaxies and the epoch of structure formation.

Physical Foundations of Cosmology
TL;DR: Inflationary cosmology has been developed over the last twenty years to remedy serious shortcomings in the standard hot big bang model of the universe as mentioned in this paper and explains the basis of modern cosmology and shows where the theoretical results come from.
