Abstract

We analyse the 145 GHz temperature map produced from the 2003 flight of BOOMERanG in search for deviations from Gaussianity. We perform a pixel space analysis computing the map's skewness, kurtosis and Minkowski functionals, as well as a Fourier space analysis computing the diagonal part the of angular bispectrum. The preliminary results presented here suggest that the data are fully consistent with the Gaussian hypothesis.
