Cosmology and galactic results from the Archeops balloon experiment

Archeops1 is a balloon-borne instrument dedicated to measuring the Cosmic Microwave Background (CMB) temperature anisotropies over a large fraction (30%) of the sky, in the (sub)millimetre domain (from 143 to 545 GHz). We summarize the results obtained using the Archeops data collected during an arctic night flight from Kiruna (Sweden) to Siberia in February 2002. These results include the detection of CMB anisotropies at higher angular resolution than the previously available Cobe maps. We also summarize the results obtained regarding the shape of the dust emission spectrum in the sub-millimeter and millimeter spectral range and the first large scale detection of polarized dust emission in our Galaxy.
