Lensing reconstruction from PLANCK sky maps: inhomogeneous noise
Duncan Hanson, Graca Rocha, Krzysztof Gorski
We discuss the effects of inhomogeneous sky-coverage on CMB lens reconstruction, focusing on application to the recently launched Planck satellite. We discuss the mean-field which…
Study of the Experimental Probe of Inflationary Cosmology (EPIC)-Intemediate Mission for NASA's Einstein Inflation Probe
James Bock, Abdullah Aljabri, Alex Amblard +35
Measurements of Cosmic Microwave Background (CMB) anisotropy have served as the best experimental probe of the early universe to date. The inflationary paradigm, inspired in part b…
Increasing evidence for hemispherical power asymmetry in the five-year WMAP data
J. Hoftuft, H. K. Eriksen, A. J. Banday +3
(Abridged)Motivated by the recent results of Hansen et al. (2008) concerning a noticeable hemispherical power asymmetry in the WMAP data on small angular scales, we revisit the dip…
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…
Bayesian component separation and CMB estimation for the 5-year WMAP temperature data
C. Dickinson, H. K. Eriksen, A. J. Banday +6
A well-tested and validated Gibbs sampling code, that performs component separation and CMB power spectrum estimation, was applied to the {\it WMAP} 5-yr data. Using a simple model…
Observing the Evolution of the Universe
James Aguirre, Alexandre Amblard, Amjad Ashoorioon +172
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the univers…
