# A high-significance detection of non-Gaussianity in the WMAP 5-yr data using directional spherical wavelets

@article{McEwen2006AHD, title={A high-significance detection of non-Gaussianity in the WMAP 5-yr data using directional spherical wavelets}, author={Jason D. McEwen and M. P. Hobson and Anthony N. Lasenby and Daniel J. Mortlock}, journal={Monthly Notices of the Royal Astronomical Society}, year={2006}, volume={388}, pages={659-662} }

We repeat the directional spherical real Morlet wavelet analysis, used previously to detect non-Gaussianity in the Wilkinson Microwave Anisotropy Probe (WMAP) 1- and 3-yr data, on the WMAP 5-yr data. The non-Gaussian signal detected previously is present in the 5-yr data at a slightly increased statistical significance of approximately 99 per cent. Localized regions that contribute most strongly to the non-Gaussian signal are found to be very similar to those detected in the previous releases…
