Deconvolution Map-Making for Cosmic Microwave Background Observations
Charmaine Armitage, Benjamin D. Wandelt
We describe a new map-making code for cosmic microwave background (CMB) observations. It implements fast algorithms for convolution and transpose convolution of two functions on th…
A Beginner's Guide to the Theory of CMB Temperature and Polarization Power Spectra in the Line-of-Sight Formalism
Yen-Ting Lin, Benjamin D. Wandelt
We present here a detailed, self--contained treatment of the mathematical formalism for describing the theory of polarized anisotropy in the cosmic microwave background. This didac…
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…
The Hot and Cold Spots in the WMAP Data are Not Hot and Cold Enough
David L. Larson, Benjamin D. Wandelt
This paper presents a frequentist analysis of the hot and cold spots of the cosmic microwave background data collected by the Wilkinson Microwave Anisotropy Probe (WMAP). We compar…
