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…
Parameters and pitfalls in dark energy models with time varying equation of state
Rahul Biswas, Benjamin D. Wandelt
Are geometrical summaries of the CMB and LSS sufficient for estimating cosmological parameters? And how does our choice of a dark energy model impact the current constraints on sta…
The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
S. Dodelson, R. Easther, S. Hanany +61
Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two pressing issues primed for…
Non-Gaussianity as a Probe of the Physics of the Primordial Universe and the Astrophysics of the Low Redshift Universe
E. Komatsu, N. Afshordi, N. Bartolo +58
A new and powerful probe of the origin and evolution of structures in the Universe has emerged and been actively developed over the last decade. In the coming decade, non-Gaussiani…
