Cold Dark Matter Models with a Cosmological Constant
Andrew R Liddle, David H Lyth, Pedro T P Viana +1
We use linear and quasi-linear perturbation theory to analyse cold dark matter models of structure formation in spatially flat models with a cosmological constant. Both a tilted sp…
Pursuing Parameters for Critical Density Dark Matter Models
Andrew R Liddle, David H Lyth, R K Schaefer +2
We present an extensive comparison of models of structure formation with observations, based on linear and quasi-linear theory. We assume a critical matter density, and study both…
The Cluster Abundance in Flat and Open Cosmologies
Pedro T P Viana, Andrew R Liddle
We use the galaxy cluster X-ray temperature distribution function to constrain the amplitude of the power spectrum of density inhomogeneities on the scale corresponding to clusters…
The Open Universe Grishchuk-Zel'dovich Effect
Juan Garcia-Bellido, Andrew R Liddle, David H Lyth +1
The Grishchuk--Zel'dovich effect is the contribution to the microwave background anisotropy from an extremely large scale adiabatic density perturbation, on the standard hypothesis…
Reconstructing the Inflaton Potential --- an Overview
James E Lidsey, Andrew R Liddle, Edward W Kolb +3
We review the relation between the inflationary potential and the spectra of density (scalar) perturbations and gravitational waves (tensor perturbations) produced, with particular…
Open Cold Dark Matter Models
Andrew R Liddle, David H Lyth, David Roberts +1
Motivated by recent developments in inflationary cosmology indicating the possibility of obtaining genuinely open universes in some models, we compare the predictions of cold dark…
