Constraints on general primordial non-Gaussianity using wavelets for the Wilkinson Microwave Anisotropy Probe 7-year data

We present constraints on the non-linear coupling parameter with the Wilkinson Microwave Anisotropy Probe (WMAP) data. We use the method based on the spherical Mexican hat wavelet to measure the parameter for three of the most interesting shapes of primordial non-Gaussianity: local, equilateral and...
