A linear filter to reconstruct the ISW effect from CMB and LSS observations
R. B. Barreiro, P. Vielva, C. Hernandez-Monteagudo +1
The extraction of a signal from some observational data sets that contain different contaminant emissions, often at a greater level than the signal itself, is a common problem in A…
WMAP 5-year constraints on fnl with wavelets
A. Curto, E. Martinez-Gonzalez, P. Mukherjee +4
We present a Gaussianity analysis of the WMAP 5-year Cosmic Microwave Background (CMB) temperature anisotropy data maps. We use several third order estimators based on the spherica…
Component separation methods for the Planck mission
S. M. Leach, J. -F. Cardoso, C. Baccigalupi +27
The Planck satellite will map the full sky at nine frequencies from 30 to 857 GHz. The CMB intensity and polarization that are its prime targets are contaminated by foreground emis…
Constraints on the non-linear coupling parameter fnl with the Archeops data
A. Curto, J. F. Macias-Perez, E. Martinez-Gonzalez +5
We present a Gaussianity analysis of the Archeops Cosmic Microwave Background (CMB) temperature anisotropy data maps at high resolution to constrain the non-linear coupling paramet…
