Dark matter from inflationary quantum fluctuations

We explore a scenario in which dark matter is a massive bosonic field, arising solely from quantum fluctuations generated during inflation. In this framework, dark matter exhibits primordial…

Astrophysical and cosmological consequences of string-inspired models

The standard model of cosmology, namely the ΛCDM model, is based on Einstein’s theory of General Relativity (GR) with a Cold Dark Matter (CDM) content and a positive cosmological constant Λ, in…

Formation of primordial black holes from warm inflation

Primordial Black Holes (PBHs) serve as a unique probe to the physics of the early Universe, particularly inflation. In light of this, we study the formation of PBHs by the collapse of overdense…

Inflationary cosmology, phase transitions and primordial power spectra

We present the results of research into inflationary cosmology. This consists firstly of a basic overview of the inflationary scenario, including the currently accepted model of inflation as being…

Aspects of inflation and the very early universe

Until recently our knowledge of the primordial curvature perturbation was relatively modest. Ever since COBE delivered its map of data we know the scalar spectrum of primordial perturbations is…

Impact of high-scale Seesaw and Leptogenesis on inflationary tensor perturbations as detectable gravitational waves

We discuss the damping of inflationary gravitational waves (GW) that re-enter the horizon before or during an epoch, where the energy budget of the universe is dominated by an unstable right handed…

Constraining inflation through joint observations of the primordial gravitational wave background

The standard cosmological model leaves many questions unanswered. An early period of accelerated expansion of the Universe, referred to as inflation, resolves these issues. It provides a means to…

Big bang nucleosynthesis and physics beyond the standard model

The Hubble expansion of galaxies, the 2.73 K black-body radiation background and the cosmic abundances of the light elements argue for a hot, dense origin of the universe - the standard big bang…

Very large scale structure in an open cosmology of cold dark matter and baryons

The standard cosmology of cold dark matter (CDM) in a flat universe with Gaussian, scale-invariant fluctuations, which is so successful in explaining the major properties of galaxies and their…

Inflation and large-scale structure formation after the Cosmic Background Explorer.

It is found that the inflationary scenario provides a good starting point for a theory of large-scale structure in the universe provided the dark matter is a combination of cold plus (10--30%) hot components.

The cosmological constant and cold dark matter

THE cold dark matter (CDM) model1–4 for the formation and distribution of galaxies in a universe with exactly the critical density is theoretically appealing and has proved to be durable, but recent…

Isocurvature cold dark matter fluctuations

According to Preskill et al. (1983), the axion field represents a particularly attractive candidate for the dark matter in the universe. In many respects it behaves like other forms of cold dark…

Large-scale structure in a universe with mixed hot and cold dark matter

A UNIVERSE whose density is dominated by cold dark matter (CDM) has been considered the standard model for large-scale structure formation1, but it has had difficulty in matching the relatively quiet…

The Inflationary Universe

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…

Microwave Anisotropies in the Light of COBE

The recent COBE measurement of anisotropies in the cosmic microwave background and the recent South Pole experiment of Gaier et al. offer an excellent opportunity to probe cosmological theories. We…

The spectrum of cosmological density fluctuations and nature of dark matter

COSMIC structure is thought to have arisen by the gravitational amplification of small density fluctuations in the early Universe. The evolution of fluctuations with specified magnitude and spectrum…

A hydrodynamic treatment of the tilted cold dark matter cosmological scenario

The evolution of structure in a postrecombination Friedmann-Robertson-Walker universe containing both gaseous baryons and cold dark matter (CDM) is studied by means of an Eulerian code coupled with a…

Cold dark matter. 2: Spatial and velocity statistics

We examine high-resolution gravitational N-body simulations of the omega = 1 cold dark matter (CDM) model in order to determine whether there is any normalization of the initial density fluctuation…
