Gravitino production in the warm inflationary scenario
A. N. Taylor, Andrew R. Liddle
We estimate the production of gravitinos during and after the end of a period of warm inflation, a model in which radiation is produced continuously as the field rolls down the pot…
Hydrodynamical simulations of the Sunyaev-Zel'dovich effect: the kinetic effect
Antonio C da Silva, Domingos Barbosa, Andrew R Liddle +1
We use hydrodynamical N-body simulations to study the kinetic Sunyaev-Zel'dovich effect. We construct sets of maps, one square degree in size, in three different cosmological model…
Apparent and actual galaxy cluster temperatures
Andrew R Liddle, Pedro T P Viana, A Kathy Romer +1
The redshift evolution of the galaxy cluster temperature function is a powerful probe of cosmology. However, its determination requires the measurement of redshifts for all cluster…
Super-horizon perturbations and preheating
Karim A. Malik, D. Wands, D. H. Lyth +1
We discuss the evolution of linear perturbations about a Friedmann-Robertson-Walker background metric, using only the local conservation of energy-momentum. We show that on suffici…
Inflationary perturbations near horizon crossing
Samuel M Leach, Andrew R Liddle
We study the behaviour of inflationary density perturbations in the vicinity of horizon crossing, using numerical evolution of the relevant mode equations. We explore two specific…
Acceleration of the Universe
Andrew R Liddle
The cosmological model best capable of fitting current observational data features two separate epochs during which the Universe is accelerating. During the earliest stages of the…
