The primary results come from 6 days of observation of a patch covering 0.22% of the sky centered near R:A: ¼ 82N5, decl: ¼ 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 hEEi signal in the range 201 < l < 1000 with a significance of 4.8 , a 2 upper limit of 8.6 K2 for any hBBi contribution, and a 2 upper limit of 7.0 K2 for the hEBi spectrum. Estimates of foreground intensity fluctuations and the nondetection of hBBi and hEBi signals rule out any significant contribution from Galactic foregrounds. The results are consistent with a CDM cosmology seeded by adiabatic perturbations.We note that this is the first detection of CMB polarization with bolometric detectors.313 112 - PublicationOpen AccessSearching for non-Gaussian signals in the BOOMERanG 2003 CMB map: Preliminary results(2007-12-01)

We perform a pixel space analysis restricted to a portion of the map chosen in view of high sensitivity, very low foreground contamination and tight control of systematic effects. We set up an estimator based on the three Minkowski functionals which relies on high quality simulated data, including non Gaussian CMB maps. We find good agreement with the Gaussian hypothesis and derive the first limits based on BOOMERanG data for the non linear coupling parameter fNL as −300 < fNL < 650 at 68% CL and −800 < fNL < 1050 at 95% CL.337 164
