Limits on Isocurvature Perturbations from Non-Gaussianity in WMAP Temperature Anisotropies
Chiaki Hikage, Kazuya Koyama, Takahiko Matsubara +2
We study the effect of primordial isocurvature perturbations on non-Gaussian properties of CMB temperature anisotropies. We consider generic forms of the non-linearity of isocurvat…

Limits on Primordial Non-Gaussianity from Minkowski Functionals of the WMAP Temperature Anisotropies
Chiaki Hikage, Takahiko Matsubara, Peter Coles +3
We present an analysis of the Minkowski Functionals (MFs) describing the WMAP three-year temperature maps to place limits on possible levels of primordial non-Gaussianity. In parti…
