A fast directional continuous spherical wavelet transform
J. D. McEwen, M. P. Hobson, A. N. Lasenby +1
A fast algorithm for Antoine and Vandergheynst's (1998) directional continuous spherical wavelet transform (CSWT) is presented. Computational requirements are reduced by a factor o…
Maximum-entropy reconstruction of gravitational lenses using shear and/or magnification data
S. L. Bridle, M. P. Hobson, Richard Saunders +1
We demonstrate that the maximum-entropy method for gravitational lens reconstruction presented in Bridle et al. (1998) may be applied even when only shear \emph{or} magnification i…
Combining Supernovae and LSS Information with the CMB
A. N. Lasenby, S. L. Bridle, M. P. Hobson
Observations of the Cosmic Microwave Background (CMB), large scale structure (LSS) and standard candles such as Type 1a Supernovae (SN) each place different constraints on the valu…
The effect of a spatially varying Galactic spectral index on the maximum entropy reconstruction of Planck Surveyor satellite data
A. W. Jones, M. P. Hobson, P. Mukherjee +1
We study the effect of Galactic foregrounds with spatially varying spectral indices on analysis of simulated data from the Planck Satellite. We also briefly mention the effect the…
Joint estimation of cosmological parameters from CMB and IRAS data
Matthew Webster, S. L. Bridle, M. P. Hobson +3
Observations of large scale structure (LSS) and the Cosmic Microwave Background (CMB) each place separate constraints on the values of cosmological parameters. We calculate a joint…
Effect of a Collapsing Cluster on the CMB temperature and Power Spectrum
Y. Dabrowski, M. P. Hobson, A. N. Lasenby +1
We present a new model for the formation of spherically symmetric clusters in an expanding Universe. Both the Universe and the collapsing cluster are governed by the same pressure…
