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…
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…
Testing Gaussianity on Archeops Data
A. Curto, J. Aumont, J. F. Macias-Perez +5
A Gaussianity analysis using a goodness-of-fit test and the Minkowski functionals on the sphere has been performed to study the measured Archeops Cosmic Microwave Background (CMB)…
