Planck Intermediate Results. I. Further validation of new Planck clusters with XMM-Newton
The Planck Collaboration, N. Aghanim, M. Arnaud +182
We present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-…
Bayesian noise estimation for non-ideal CMB experiments
I. K. Wehus, S. K. Næss, H. K. Eriksen
We describe a Bayesian framework for estimating the time-domain noise covariance of CMB observations, typically parametrized in terms of a 1/f frequency profile. This framework is…
Analysis of WMAP 7-year Temperature Data: Astrophysics of the Galactic Haze
Davide Pietrobon, Krzysztof M. Gorski, James Bartlett +10
We analyse WMAP 7-year temperature data, jointly modeling the cosmic microwave background (CMB) and Galactic foreground emission. We use the Commander code based on Gibbs sampling.…
Planck Early Results XXVI: Detection with Planck and confirmation by XMM-Newton of PLCK G266.6-27.3, an exceptionally X-ray luminous and massive galaxy cluster at z~1
Planck Collaboration, N. Aghanim, M. Arnaud +189
We present first results on PLCK G266.6-27.3, a galaxy cluster candidate detected at a signal-to-noise ratio of 5 in the Planck All Sky survey. An XMM-Newton validation observation…
Comment on "CCC-predicted low-variance circles in CMB sky and LCDM"
H. K. Eriksen, I. K. Wehus
In a recent preprint ("CCC-predicted low-variance circles in the CMB sky and LCDM"), Gurzadyan and Penrose (2011) claim for the second time to find evidence for pre-Big Bang activi…
Large-Scale Polarized Foreground Component Separation for Planck
Charmaine Armitage-Caplan, Joanna Dunkley, Hans Kristian Eriksen +1
We use Bayesian component estimation methods to examine the prospects for large-scale polarized map and cosmological parameter estimation with simulated Planck data assuming simpli…
