We have calculated the third order moments of scalar curvature perturbations in configuration space for different inflationary models. We developed a robust numerical technique to compute the bispectrum for different models that have some features in the inflationary potential. From the bispectrum we evaluated moments analytically in the slow roll regime while we devised a numerical mechanism to calculated these moments for non slow roll single field inflationary models with standard kinetic… 

Inflationary study of non-Gaussianity using two-dimensional geometrical measures of CMB temperature maps

In this work we effectively calculated the two-dimensional Minkowski functionals for cosmic microwave background (CMB) temperature maps generated by single field models of inflation with a standard

Numerical prescriptions of early-time divergences of the in-in formalism

In quantum field theory, the in and out states can be related to the full Hamiltonian by the iϵ prescription. A Wick rotation can further bring the correlation functions to Euclidean spacetime where

A Study on the Baryon Acoustic Oscillation with Topological Data Analysis

(abridged) The scale of the acoustic oscillation of baryons at the baryon-photon decoupling is imprinted on the spatial distribution of galaxies in the Universe, known as the baryon acoustic



Non-gaussian signatures of general inflationary trajectories

We carry out a numerical calculation of the bispectrum in generalised trajectories of canonical, single-field inflation. The trajectories are generated in the Hamilton-Jacobi (HJ) formalism based on

Primordial non-Gaussianities in single-field inflation

We calculate the three-point function for primordial scalar fluctuations in a single-field inflationary scenario where the scalar field Lagrangian is a completely general function of the field and

Large non-Gaussianities in single-field inflation

While adding features to a potential can improve the fit to the two-point function, these are generically associated with a greatly enhanced signal at the three-point level, which may lead to a consistency check on models of inflation with non-smooth potentials.

Generation and characterization of large non-Gaussianities in single field inflation

Two distinct mechanisms by which a non-trivial potential can generate large non-Gaussianities are discussed, and a significantly improved approach to regularizing and numerically evaluating the integrals that contribute to the three-point function is presented.

Non-Gaussian features of primordial fluctuations in single field inflationary models

We compute the three point correlation functions for primordial scalar and tensor fluctuations in single field inflationary models. We obtain explicit expressions in the slow roll limit where the

Large slow-roll corrections to the bispectrum of noncanonical inflation

Nongaussian statistics are a powerful discriminant between inflationary models, particularly those with noncanonical kinetic terms. Focusing on theories where the Lagrangian is an arbitrary

A note on the role of the boundary terms for the non-Gaussianity in general k-inflation

In this short note we clarify the role of the boundary terms in the calculation of the leading order tree-level bispectrum in a fairly general minimally coupled single field inflationary model, where

Non-Gaussian extrema counts for CMB maps

In the context of the geometrical analysis of weakly non-Gaussian cosmic microwave background maps, the 2D differential extrema counts as functions of the excursion set threshold is derived from the

Non-Gaussian statistics of critical sets in 2D and 3D: Peaks, voids, saddles, genus, and skeleton

The formalism to compute the geometrical and topological one-point statistics of mildly non-Gaussian 2D and 3D cosmological fields is developed. Leveraging the isotropy of the target statistics, the

Statistics of Smoothed Cosmic Fields in Perturbation Theory. I. Formulation and Useful Formulae in Second-Order Perturbation Theory

We formulate a general method for perturbative evaluations of statistics of smoothed cosmic fields and provide useful formulae for application of the perturbation theory to various statistics. This
