Non-linear Preheating with Scalar Metric Perturbations
M. Bastero-Gil, M. Tristram, J. Macias-Perez +1
We have studied preheating of field perturbations in a 3-dimensional lattice including the effect of scalar metric perturbations, in two generic models of inflation: chaotic inflat…
Data analysis methods for the cosmic microwave background
Matthieu Tristram, Ken Ganga
In this review, we give an overview of some of the major aspects of data reduction and analysis for the cosmic microwave background (CMB). Since its prediction and discovery in the…
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)…
Archeops In-flight Performance, Data Processing and Map Making
J. F. Macias-Perez, G. Lagache, B. Maffei +69
Archeops is a balloon--borne experiment widely inspired by the Planck satellite and by its High Frequency Instrument (HFI). It is mainly dedicated to measure the Cosmic Microwave B…
The CMB temperature power spectrum from an improved analysis of the Archeops data
M. Tristram, G. Patanchon, J. F. Macias-Perez +47
We present improved results on the measurement of the angular power spectrum of the Cosmic Microwave Background (CMB) temperature anisotropies using the data from the last Archeops…
Xspect, estimation of the angular power spectrum by computing cross-power spectra with analytical error bars
M. Tristram, J. F. Macias-Perez, C. Renault +1
We present Xspect, a method to obtain estimates of the angular power spectrum of the Cosmic Microwave Background (CMB) temperature anisotropies including analytical error bars deve…
