Even simple inflationary scenarios have many free parameters. Beyond the variables appearing in the inflationary action, these include dynamical initial conditions, the number of fields, and couplings to other sectors. These quantities are often ignored but cosmological observables can depend on the unknown parameters. We use Bayesian networks to account for a large set of inflationary parameters, deriving generative models for the primordial spectra that are conditioned on a hierarchical set…

Expectations for inflationary observables: simple or natural?
We describe the general inflationary dynamics that can arise with a single, canonically coupled field where the inflaton potential is a 4-th order polynomial. This scenario yields a wide range of
Manyfield Inflation in Random Potentials
We construct models of inflation with many randomly interacting fields and use these to study the generation of cosmological observables. We model the potentials as multi-dimensional Gaussian random
Seven lessons from manyfield inflation in random potentials
We study inflation in models with many interacting fields subject to randomly generated scalar potentials. We use methods from non-equilibrium random matrix theory to construct the potentials and an
Cosmological Inflation in N-Dimensional Gaussian Random Fields with Algorithmic Data Compression
The Gaussian random potential is a highly versatile inflationary model with a rich volume of parameter space capable of reproducing modern observations and is found to be maximally random.
Effect of reheating on predictions following multiple-field inflation
We study the sensitivity of cosmological observables to the reheating phase following inflation driven by many scalar fields. We describe a method which allows semianalytic treatment of the impact of
Predictions After Many-field Reheating
We study the sensitivity of cosmological observables to the reheating phase following inflation driven by many scalar fields. We describe a method which allows semi-analytic treatment of the impact
Inflation as an information bottleneck: a strategy for identifying universality classes and making robust predictions
A statistical approach to handling sources of theoretical uncertainty in string theory models of inflation is proposed and universality with respect to a number of model parameters is found and that consistency with observational constraints implies that with very high probability certain perturbative corrections are non-negligible.
Curvature perturbations from stochastic particle production during inflation
We calculate the curvature power spectrum sourced by spectator fields that are excited repeatedly and non-adiabatically during inflation. In the absence of detailed information of the nature of
Vacuum Selection on Axionic Landscapes
We compute the distribution of minima that are reached dynamically on multi-field axionic landscapes, both numerically and analytically. Such landscapes are well suited for inflationary model
Squeezed Bispectrum in the δN Formalism : Local Observer Effect in Field Space
The prospects of future galaxy surveys for non-Gaussianity measurements call for the development of robust techniques for computing the bispectrum of primordial cosmological perturbations. In this


Bayesian Analysis of Inflation II: Model Selection and Constraints on Reheating
The model selection problem for inflationary cosmology is discussed, and it is confirmed that while present-day data tightly constrains the properties of the power spectrum, it cannot usefully distinguish between the members of a large class of simple inflationary models.
N-flation: multifield inflationary dynamics and perturbations
We carry out numerical investigations of the dynamics and perturbations in the Nflation model of Dimopoulos et al. (2005). This model features large numbers of scalar fields with different masses,
Bayesian Analysis of Inflation: Parameter Estimation for Single Field Models
Future astrophysical data sets promise to strengthen constraints on models of inflation, and extracting these constraints requires methods and tools commensurate with the quality of the data. In this
Simple predictions from multifield inflationary models.
The expected amplitude of isocurvature perturbations grows with N, raising the possibility that many-field models may be sensitive to postinflationary physics and suggesting new avenues for testing these scenarios.
Inflation and the scale dependent spectral index: prospects and strategies
We consider the running of the spectral index as a probe of both inflation itself, and of the overall evolution of the very early universe. Surveying a collection of simple single field inflationary
Initial conditions and sampling for multifield inflation
We investigate the initial conditions problem for multifield inflation. In these scenarios the pre-inflationary dynamics can be chaotic, increasing the sensitivity of the onset of inflation to the
Bayesian evidence of the post-Planck curvaton
We perform a Bayesian model comparison for scenarios within the quadratic curvaton model, determining the degree to which both are disfavoured with respect to the ΛCDM concordance model and
Bayesian Analysis of Inflation III: Slow Roll Reconstruction Using Model Selection
We implement Slow Roll Reconstruction – an optimal solution to the inverse problem for inflationary cosmology – within ModeCode, a publicly available solver for the inflationary dynamics. We obtain
Predictions in multifield models of inflation
This paper presents a method for obtaining an analytic expression for the density function of observables in multifield models of inflation with sum-separable potentials. The most striking result is
Inflating an Inhomogeneous Universe
While cosmological inflation can erase primordial inhomogeneities, it is possible that inflation may not begin in a significantly inhomogeneous universe. This issue is particularly pressing in
