THE COSMIC MICROWAVE BACKGROUND Archeops results
نویسنده
چکیده
ARCHEOPS is a balloon–borne instrument dedicated to measuring cosmic microwave background (CMB) temperature anisotropies at high angular resolution (∼ 12 arcmin.) over a large fraction (30%) of the sky in the (sub)millimetre domain (from 143 to 545 GHz). We describe the results obtained during the last flight: the ARCHEOPS estimate of the CMB angular power spectrum linking for the first time COBE scales and the first acoustic peak, consequences in terms of cosmological parementers favouring a flat-Λ Universe. We also present the first measurement of galactic dust polarization and accurate maps of the galactic plane diffuse (sub) millimetre emisson. c © 2003 Académie des sciences

Archeops: a large sky coverage millimeter experiment for mapping Cosmic Microwave Background anisotropies
We present Archeops, a balloon-borne bolometer experiment designed to map a large part of the sky at millimeter and submillimeter wavelengths. The main scientific goal is to study the Cosmic Microwave Background anisotropies on all scales, in order to properly derive the cosmological parameters of the Universe. We present the sky coverage map of the first scientific flight.
متن کاملTesting Gaussianity on Archeops Data
Aims. A Gaussianity analysis using a goodness-of-fit test has been performed to study the measured Archeops Cosmic Microwave Background (CMB) temperature anisotropy data for a 143 GHz Archeops bolometer. We consider large angular scales, greater than 1.8 degrees, and a large fraction of the North Galactic hemisphere, around 16%, with a galactic latitude b > 15 degrees. Methods. The considered g...

Archeops is a balloon–borne instrument dedicated to measuring cosmic microwave background (CMB) temperature anisotropies at high angular resolution (∼ 8 arcminutes) over a large fraction (∼ 30%) of the sky in the millimetre domain. The general design is based on Planck High Frequency Instrument (HFI) technology. Bolometers cooled to 0.1 K scan the sky in total power mode along large circles at ...
متن کاملArcheops ’ results on the Cosmic Microwave Background
Archeops is a balloon–borne experiment dedicated to the measurement of the temperature anisotropies of the cosmic microwave background (CMB) from large angular scales to about 10 arcminutes. A brief introduction to the CMB is given below, followed by a description of the Archeops experiment. Archeops flew on the 7th of February 2002 in the Arctic night from Kiruna (Sweden) to Russia. The analys...
متن کاملConstraints on the non-linear coupling parameter fnl with the Archeops data
Aims. We present a Gaussianity analysis of the Archeops Cosmic Microwave Background (CMB) temperature anisotropies data maps at high resolution to constrain the non-linear coupling parameter fnl characterising well motivated non-Gaussian CMB models. We used the data collected by the most sensitive Archeops bolometer at 143 GHz to perform this analysis. For this purpose, the instrumental noise w...
