These four lectures cover four topics in modern cosmology: the cosmological constant, the cosmic microwave background, inflation, and cosmology at the Planck scale. The underlying theme is that cosmology gives us a unique window on the “physics of nothing,” or vacuum energy. The theory of inflation postulates that vacuum energy, or something very much like it, was the dominant force shaping the evolution of the very early universe. Recent astrophysical observations indicate that vacuum energy… 
Inflationary cosmology: from theory to observations
The main aim of this paper is to provide a qualitative introduction to the cosmological inflation theory and its relationship with current cosmological observations. The inflationary model solves
Viscous Cosmology for Early- and Late-Time Universe
From a hydrodynamicist’s point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all an abstraction
Unification, the Big Bang, and the Cosmological Constant
The two major goals in fundamental physics are: 1) Unification of all forces incorporating relativity and quantum theory, 2) Understanding the origin and evolution of the Universe as well as
ΛCDM Cosmology + Chaotic Inflation
ΛCDM COSMOLOGY + CHAOTIC INFLATION By Peter Alexander Farago A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science at Virginia Commonwealth University.
Predictions of Spectral Parameters by Several Inflationary Universe Models in Light of the Planck Results
I give a review of predictions of values of spectral parameters for a large number of inflationary models. The present review includes detailed deductions and information about the approximations
Small-scale anisotropies of the cosmic microwave background: Experimental and theoretical perspectives
In this thesis, we consider both theoretical and experimental aspects of the cosmic microwave background (CMB) anisotropy for l > 500. Part one addresses the process by which the universe first
Early universe cosmology in supersymmetric extensions of the standard model
In his thesis we investigate possible connections between cosmological in ation and lepto- genesis on the one side and particle physics on the other side. We work in supersymmetric extensions of the
Primordial Gravitational Waves from Axion-Gauge Fields Dynamics
Inspired by the chromo-natural inflation model of Adshead&Wyman, we reshape its scalar content to relax the tension with current observational bounds. Besides an inflaton, the setup includes a
Enhancement of non-gaussianity after inflation
We study the evolution of cosmological perturbations on large scales, up to second order, for a perfect fluid with generic equation of state. Taking advantage of super-horizon conservation laws, it
A Covariant Natural Ultraviolet Cutoff in Inflationary Cosmology
In the field of quantum gravity, it is widely expected that some form of a minimum length scale, or ultraviolet cutoff, exists in nature. Recently, a new natural ultraviolet cutoff that is fully


Particle Physics and Inflationary Cosmology
With the invention of unified theories of strong, weak, electromagnetic and gravitational interactions, elementaryparticle physics has entered a very interesting and unusual stage of its development.
The cosmological constant is back
A diverse set of observations now compellingly suggest that the universe possesses a nonzero cosmological constant. In the context of quantum-field theory a cosmological constant corresponds to the
Cosmological imprint of an energy component with general equation of state
We examine the possibility that a significant component of the energy density of the Universe has an equation of state different from that of matter, radiation, or cosmological constant ({Lambda} ).
Constraining Inflation with Cosmic Microwave Background Polarization
Observations of the polarization of the cosmic microwave backround (CMB) have the potential to place much tighter constraints on cosmological parameters than observations of the fluctuations in
Cosmological Perturbation Theory in the Synchronous and Conformal Newtonian Gauges
This paper presents a systematic treatment of the linear theory of scalar gravitational perturbations in the synchronous gauge and the conformal Newtonian (or longitudinal) gauge. It differs from
A Note on inflation and transPlanckian physics
In this paper we consider the influence of trans-Planckian physics on the CMBR anisotropies produced by inflation. We consider a simple toy model that allows for analytic calculations and argue on
A flat Universe from high-resolution maps of the cosmic microwave background radiation
The first images of resolved structure in the microwave background anisotropies over a significant part of the sky are reported, consistent with that expected for cold dark matter models in a flat (euclidean) Universe, as favoured by standard inflationary models.
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
