Abstract

I will review some recent claims of anomalous signatures in the WMAP data of the CMB - specifically those that indicate a departure from Statistical Isotropy. This will include an outline of various methods of analysis and the issues involved in testing the Gaussianity and Statistical Isotropy of the CMB. I will then discuss the various implications of the observations - the most exciting of which is that our Universe is not Isotropic and more complicated cosmological models need to be considered.
