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…
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…
Hydrodynamical simulations of the Sunyaev--Zel'dovich effect
Antonio C da Silva, Domingos Barbosa, Andrew R Liddle +1
We use a hydrodynamical N-body code to generate simulated maps, of size one square degree, of the thermal SZ effect. We study three different cosmologies; the currently-favoured lo…
Inflaton potential reconstruction without slow-roll
Ian J Grivell, Andrew R Liddle
We describe a method of obtaining the inflationary potential from observations which does not use the slow-roll approximation. Rather, the microwave anisotropy spectrum is obtained…
