Observational and theoretical issues in early universe cosmology

In this thesis we evaluate and compare competing cosmological models for empirical and theoretical consistency and identify new ways of improving current paradigms of early universe cosmology. In the

Reconciliation of high energy scale models of inflation with Planck

The inflationary cosmology paradigm is very successful in explaining the CMB anisotropy to the percent level. Besides the dependence on the inflationary model, the power spectra, spectral tilt and

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

Inflationary paradigm after Planck 2013

A viable Starobinsky-like inflationary scenario in the light of Planck and BICEP2 results

The recent CMB data from Planck and BICEP2 observations have opened a new window for inflationary cosmology. In this paper, we compare three Starobinsky-like inflationary scenarios: (i) The original

Hybrid inflation in the complex plane

Supersymmetric hybrid inflation is an exquisite framework to connect inflationary cosmology to particle physics at the scale of grand unification. Ending in a phase transition associated with

BICEP2, Planck, spinorial space-time, pre-Big Bang.

The field of Cosmology is currently undergoing a positive and constructive crisis. Controversies concerning inflation are not really new. But after the 2013-2014 Planck and BICEP2 announcements, and

The best inflationary models after Planck

TLDR
This analysis singles out the most probable models (from an Occam's razor point of view) that are compatible with Planck data, while ruling out with very strong evidence 34% of the models considered.

Inflationary universe: A possible solution to the horizon and flatness problems

The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: (1) The early universe is assumed to be highly homogeneous, in spite of the fact that

Inflationary Theory and Alternative Cosmology

Recently Hollands and Wald argued that inflation does not solve any of the major cosmological problems. We explain why we disagree with their arguments. They also proposed a new speculative mechanism

Eternal inflation and its implications

I summarize the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the

On the Degree of Generality of Inflation in Friedmann Cosmological Models with a Massive Scalar Field

Friedmann cosmological models with a massive minimally coupled scalar field are investigated by numerical methods. It is indicated that the majority of the solutions undergo the inflationary stage in

TLDR
Non-minimal coupling may provide a relatively simple solution to the long-standing problem of excessive density perturbations in inflationary models.

Can the universe afford inflation

Cosmic inflation is envisioned as the 'most likely' start for the observed universe. To give substance to this claim, a framework is needed in which inflation can compete with other scenarios and the

Higgs-dilaton cosmology: From the early to the late Universe

We consider a minimal scale-invariant extension of the standard model of particle physics combined with unimodular gravity formulated in [M. Shaposhnikov and D. Zenhausern, Phys. Lett. B 671, 187

Higgs inflation: consistency and generalisations

We analyse the self-consistency of inflation in the Standard Model, where the Higgs field has a large non-minimal coupling to gravity. We determine the domain of energies in which this model

Prescription for probabilities in eternal inflation

Some of the parameters we call ‘‘constants of nature’’ may in fact be variables related to the local values of some dynamical fields. During inflation, these variables are randomized by quantum
