Archeops' 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. Archeo...
