TL;DR: Non-Gaussianity, i.e., the study of nonGaussian contributions to the correlations of cosmological fluctuations, will become an important probe of both the early and the late Universe as discussed by the authors.
Journal ArticleDOI
Primordial black holes and generalized constraints on chaotic inflation.
Bernard Carr,James E. Lidsey +1 more
TL;DR: A general prescription for realizing successful inflation in chaotic inflation in terms of a set of constraints on this function of the inflaton field φ is derived.
Journal ArticleDOI
Reconstructing the inflaton potential: In principle and in practice.
Edmund J. Copeland,Edward W. Kolb,Edward W. Kolb,Andrew R. Liddle,James E. Lidsey,James E. Lidsey +5 more
TL;DR: A full reconstruction of the functional form of the potential will not be possible within the foreseeable future, but with a knowledge of the dark matter components, it should soon be possible to combine intermediate-scale data with measurements of large-scale cosmic microwave background anisotropies to yield useful information regarding the potential.
Journal ArticleDOI
Reconstructing the inflaton potential: Perturbative reconstruction to second order
TL;DR: Here, complete expressions for the second-order contributions to the coefficients of the expansion are calculated by including for the first time corrections to the standard expression for the perturbation spectra, indicating the expected accuracy of the reconstruction.
Journal ArticleDOI
Correspondence between loop-inspired and braneworld cosmology
TL;DR: In this article, a dynamical correspondence can be established between these two paradigms at the level of the effective field equations, which allows qualitatively similar features between the two approaches to be compared and contrasted as well as providing a framework for viewing braneworld scenarios in terms of constrained Hamiltonian systems.
