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…
Early cosmology and the stochastic gravitational wave background
Luis E Mendes, Andrew R Liddle
The epoch when the Universe had a temperature higher than a GeV is long before any time at which we have reliable observations constraining the cosmological evolution. For example,…
On the formation of non-topological string networks
Ana Achúcarro, Julian Borrill, Andrew R. Liddle
We review recent simulations of the formation of a particular class of non-topological defects known as semilocal strings during a phase transition. Semilocal strings have properti…
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…
Black holes and gravitational waves in concert - a probe of superstring cosmology
Edmund J. Copeland, Andrew R. Liddle, James E. Lidsey +1
Two strands of observational gravitation, one the search for astrophysical evidence of primordial black holes and the other the search for gravitational waves, may combine to provi…
