Map-making methods for Cosmic Microwave Background experiments
Xavier Dupac, Martin Giard
The map-making step of Cosmic Microwave Background data analysis involves linear inversion problems which cannot be performed by a brute force approach for the large timelines of t…
Iterative map-making methods for Cosmic Microwave Background data analysis
Xavier Dupac
The map-making process of Cosmic Microwave Background data involves linear inversion problems which cannot be performed by a brute force approach for the large timelines of most mo…
Archeops: A High Resolution, Large Sky Coverage Balloon Experiment for Mapping CMB Anisotropies
A. Benoit, P. Ade, A. Amblard +3
Archeops is a balloon-borne instrument dedicated to measuring cosmic microwave background (CMB) temperature anisotropies at high angular resolution (8 arcminutes) over a large frac…
Submillimeter mapping and analysis of cold dust condensations in the Orion M42 star forming complex
Xavier Dupac, M. Giard, J. -P. Bernard +6
We present here the continuum submillimeter maps of the molecular cloud around the M42 Nebula in the Orion region. These have been obtained in four wavelength bands (200, 260, 360…
Analysis of ProNaOS submillimeter maps in the M42 Orion Nebula - Temperature - spectral index inverse correlation in several regions
Xavier Dupac, M. Giard, J. -P. Bernard +5
We have mapped with the French submillimeter balloon-borne telescope ProNaOS the thermal emission of the dust in the M42 Orion Nebula. The map obtained is 50' by 40' with an angula…
How to make CMB maps from huge timelines with small computers
Xavier Dupac, Martin Giard
We present in this article two different ways to make CMB maps in practice, from large timelines. One is to make a simple destriping, fitting the data and using the scan intercepts…
