WMAP5 constraints on the unified model of dark energy and dark matter
T. Barreiro, O. Bertolami, P. Torres
We derive constraints on the parameter space of the unified model of dark energy and dark matter, the Generalized Chaplygin Gas (GCG), from the amplitudes and positions of the firs…
Quintessence arising from exponential potentials
T. Barreiro, E. J. Copeland, N. J. Nunes
We demonstrate how exponential potentials that could arise in the early Universe as a result of Kaluza-Klein type compactifications of string theory, can lead to cosmological solut…
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…
