Super-horizon perturbations and preheating
Andrew R. Liddle, David H. Lyth, Karim A. Malik +1
It has recently been claimed by Bassett et al that preheating after inflation may affect the amplitude of curvature perturbations on large scales, undermining the usual inflationar…
Perturbation amplitude in isocurvature inflation scenarios
Andrew R Liddle, Anupam Mazumdar
We make a detailed calculation of the amplitude of isocurvature perturbations arising from inflationary models in which the cold dark matter is represented by a scalar field which…
The dearth of halo dwarf galaxies: is there power on short scales?
Marc Kamionkowski, Andrew R. Liddle
N-body simulations of structure formation with scale-invariant primordial perturbations show significantly more virialized objects of dwarf-galaxy mass in a typical galactic halo t…
A Serendipitous Galaxy Cluster Survey with XMM: Expected Catalogue Properties and Scientific Applications
A. Kathy Romer, Pedro T. P. Viana, Andrew R. Liddle +1
This paper describes a serendipitous galaxy cluster survey that we plan to conduct with the XMM X-ray satellite. We have modeled the expected properties of such a survey for three…
Dynamics and perturbations in assisted chaotic inflation
Nemanja Kaloper, Andrew R. Liddle
On compactification from higher dimensions, a single free massive scalar field gives rise to a set of effective four-dimensional scalar fields, each with a different mass. These ca…
Observational tests of inflation
Andrew R Liddle
We are on the verge of the first precision testing of the inflationary cosmology as a model for the origin of structure in the Universe. I review the key predictions of inflation w…
