# A New Probe of Gaussianity and Isotropy for CMB Maps

26 Nov 2019J. HamannQ. T. Le GiaI. H. SloanY. G. WangR. S. Womersley

We introduce a new mathematical tool (a direction-dependent probe) to analyse the randomness of purported isotropic Gaussian random fields on the sphere. We apply the probe to assess the full-sky cosmic microwave background (CMB) temperature maps produced by the {\it Planck} collaboration (PR2 2015 and PR3 2018), with special attention to the inpainted maps...
