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-…
The effect of the linear term on the wavelet estimator of primordial non-Gaussianity
A. Curto, E. Martinez-Gonzalez, R. B. Barreiro
In this work we present constraints on different shapes of primordial non-Gaussianity using the Wilkinson Microwave Anisotropy Probe (WMAP) 7-year data and the spherical Mexican ha…
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…
Constraints on general primordial non-Gaussianity using wavelets for the Wilkinson Microwave anisotropy probe 7-year data
A. Curto, E. Martinez-Gonzalez, R. B. Barreiro +1
We present constraints on the non-linear coupling parameter fnl with the Wilkinson Microwave Anisotropy Probe (WMAP) data. We use the method based on the spherical Mexican hat wave…
Multi-resolution internal template cleaning: An application to the Wilkinson Microwave Anisotropy Probe 7-yr polarization data
R. Fernández-Cobos, P. Vielva, R. B. Barreiro +1
Cosmic microwave background (CMB) radiation data obtained by different experiments contain, besides the desired signal, a superposition of microwave sky contributions. We present a…
Constraints on fNL from Wilkinson Microwave Anisotropy Probe 7-year data using a neural network classifier
B. Casaponsa, M. Bridges, A. Curto +3
We present a multi-class neural network (NN) classifier as a method to measure nonGaussianity, characterised by the local non-linear coupling parameter fNL, in maps of the cosmic m…
