Bayesian analysis of an anisotropic universe model: systematics and polarization
Nicolaas E. Groeneboom, Lotty Ackerman, Ingunn Kathrine Wehus +1
We revisit the anisotropic universe model previously developed by Ackerman, Carroll and Wise (ACW), and generalize both the theoretical and computational framework to include polar…
A self-contained guide to the CMB Gibbs sampler
Nicolaas E. Groeneboom
We present a consistent self-contained and pedagogical review of the CMB Gibbs sampler, focusing on computational methods and code design. We provide an easy-to-use CMB Gibbs sampl…
The effect of asymmetric beams in the Wilkinson Microwave Anisotropy Probe experiment
Ingunn Kathrine Wehus, Lotty Ackerman, H. K. Eriksen +1
We generate simulations of the CMB temperature field as observed by the WMAP satellite, taking into account the detailed shape of the asymmetric beams and scanning strategy of the…
Bayesian analysis of white noise levels in the 5-year WMAP data
N. E. Groeneboom, H. K. Eriksen, K. Gorski +3
We develop a new Bayesian method for estimating white noise levels in CMB sky maps, and apply this algorithm to the 5-year WMAP data. We assume that the amplitude of the noise RMS…
