Evidence of primordial non-Gaussianity (fNL) in the Wilkinson microwave anisotropy probe 3-year data at 2.8sigma

Evidence of primordial non-Gaussianity (fNL) in the Wilkinson microwave anisotropy probe 3-year data at 2.8sigma

We present evidence for primordial non-Gaussianity of the local type (fNL) in the temperature anisotropy of the cosmic microwave background. Analyzing the bispectrum of the Wilkinson Microwave Anisotropy Probe 3-year data up to lmax=750 we find 27
