A Bayesian analysis of the primordial power spectrum
M. Bridges, A. N. Lasenby, M. P. Hobson
We present a Bayesian analysis of large-scale structure and cosmic microwave background data to constrain the form of the primordial power spectrum. We have extended the usual pres…
A VSA search for the extended Sunyaev-Zel'dovich Effect in the Corona Borealis Supercluster
Ricardo Genova-Santos, Jose Alberto Rubino-Martin, Rafael Rebolo +16
We present interferometric imaging at 33 GHz of the Corona Borealis supercluster, using the extended configuration of the Very Small Array. A total area of 24 deg^2 has been imaged…
Fast directional continuous spherical wavelet transform algorithms
J. D. McEwen, M. P. Hobson, D. J. Mortlock +1
We describe the construction of a spherical wavelet analysis through the inverse stereographic projection of the Euclidean planar wavelet framework, introduced originally by Antoin…
Effect of component separation on the temperature distribution of the CMB
R. B. Barreiro, E. Martinez-Gonzalez, P. Vielva +1
We present a study of the effect of component separation on the recovered cosmic microwave background (CMB) temperature distribution, considering Gaussian and non-Gaussian input CM…
