Applications of Fast Convolution on the Sphere
K. M. Huffenberger, I. J. O'Dwyer, K. M. Gorski +1
We present several diverse applications of the spherical fast convolution method suggested by Wandelt and Gorski (2001), which is useful for studies of telescope optical properties…
Estimation of Polarized Power Spectra by Gibbs sampling
D. L. Larson, H. K. Eriksen, B. D. Wandelt +4
Earlier papers introduced a method of accurately estimating the angular cosmic microwave background (CMB) temperature power spectrum based on Gibbs sampling. Here we extend this fr…
A re-analysis of the three-year WMAP temperature power spectrum and likelihood
H. K. Eriksen, Greg Huey, R. Saha +11
We analyze the three-year WMAP temperature anisotropy data seeking to confirm the power spectrum and likelihoods published by the WMAP team. We apply five independent implementatio…
Angular power spectrum of the FastICA CMB component from BEAST data
S. Donzelli, D. Maino, M. Bersanelli +9
We present the angular power spectrum of the CMB component extracted with FastICA from the Background Emission Anisotropy Scanning Telescope (BEAST) data. BEAST is a 2.2 meter off-…
Power spectrum estimation from high-resolution maps by Gibbs sampling
H. K. Eriksen, I. J. O'Dwyer, J. B. Jewell +6
We revisit a recently introduced power spectrum estimation technique based on Gibbs sampling, with the goal of applying it to the high-resolution WMAP data. In order to facilitate…
Bayesian Power Spectrum Analysis of the First-Year WMAP data
I. J. O'Dwyer, H. K. Eriksen, B. D. Wandelt +6
We present the first results from a Bayesian analysis of the WMAP first year data using a Gibbs sampling technique. Using two independent, parallel supercomputer codes we analyze t…
