Abstract

We report measurements of the CMB polarization power spectra from the 2003 January Antarctic flight of BOOMERANG. The primary results come from 6 days of observation of a patch covering 0.22% of the sky centered near R.A. = 82°.5, decl. = -45°. The observations were made using four pairs of polarization-sensitive bolometers operating in bands centered at 145 GHz. Using two independent analysis pipelines, we measure a nonzero 〈EE〉 signal in the range 201 < l < 1000 with a significance of 4.8 σ, a 2 σ upper limit of 8.6 μK² for any 〈BB〉 contribution, and a 2 σ upper limit of 7.0 μK² for the 〈EB〉 spectrum. Estimates of foreground intensity fluctuations and the non-detection of 〈BB〉 and 〈EB〉 signals rule out any significant contribution from Galactic foregrounds. The results are consistent with a ΛCDM cosmology seeded by adiabatic perturbations. We note that this is the first detection of CMB polarization with bolometric detectors.
