Probing the primordial power spectrum with the VSA (and other CMB experiments)
Richard A. Battye, the VSA Collaboration
We present estimates of parameters which model the primordial density fluctuations using CMB data from the VSA, 1st year WMAP, CBI and ACBAR along with external priors from 2dF and…
Estimating the bispectrum of the Very Small Array data
Sarah Smith, Graca Rocha, Anthony Challinor +30
We estimate the bispectrum of the Very Small Array data from the compact and extended configuration observations released in December 2002, and compare our results to those obtaine…
Sunyaev-Zel'dovich cluster surveys using a large beam
Richard A. Battye, Jochen Weller
Sunyaev Zel'dovich cluster surveys can be used to constrain cosmological parameters. Extracting clusters from the primary anisotropies and the unresolved background from very faint…
Axion string cosmology and its controversies
R. A. Battye, E. P. S. Shellard
Understanding axion cosmology has important experimental consequences since it constrains the range of allowed values for the axion mass. In the standard thermal scenario, which as…
Domain Wall Dominated Universes
Richard A. Battye, Martin Bucher, David Spergel
We consider a cosmogony with a dark matter component consisting of a network of frustrated domain walls. Such a network provides a solid dark matter component with that…
Early structure formation with cold plus hot dark matter --- a success of strings plus inflation model
Richard A. Battye, Joao Magueijo, Jochen Weller
Quantum fluctuations created during inflation can account for the observed matter distribution in the linear regime if the universe has two components of dark matter, one which is…
