Cosmic microwave background constraints on the epoch of reionization
Louise M Griffiths, Domingos Barbosa, Andrew R Liddle
We use a compilation of cosmic microwave anisotropy data to constrain the epoch of reionization in the Universe, as a function of cosmological parameters. We consider spatially-fla…
A classification of scalar field potentials with cosmological scaling solutions
Andrew R Liddle, Robert J Scherrer
An attractive method of obtaining an effective cosmological constant at the present epoch is through the potential energy of a scalar field. Considering models with a perfect fluid…
Inflation during oscillations of the inflaton
Andrew R Liddle, Anupam Mazumdar
Damour and Mukhanov have recently devised circumstances in which inflation may continue during the oscillatory phase which ensues once the inflaton field reaches the minimum of its…
Assisted inflation
Andrew R Liddle, Anupam Mazumdar, Franz E Schunck
In inflationary scenarios with more than one scalar field, inflation may proceed even if each of the individual fields has a potential too steep for that field to sustain inflation…
Inflation and the microwave background
Andrew R Liddle
I discuss the interplay between inflation and microwave background anisotropies, stressing in particular the accuracy with which inflation predictions need to be made, and the impo…
Galaxy clusters at 0.3 < z < 0.4 and the value of Ω_0
Pedro T P Viana, Andrew R Liddle
The observed evolution of the galaxy cluster X-ray integral temperature distribution function between and is used in an attempt to constrain the value of the dens…
