Angular Trispectrum of CMB Temperature Anisotropy from Primordial Non-Gaussianity with the Full Radiation Transfer Function
Noriyuki Kogo, Eiichiro Komatsu
We calculate the cosmic microwave background (CMB) angular trispectrum, spherical harmonic transform of the four-point correlation function, from primordial non-Gaussianity in prim…
Constraining Cosmological Parameters by the Cosmic Inversion Method
Noriyuki Kogo, Misao Sasaki, Jun'ichi Yokoyama
We investigate the question of how tightly we can constrain the cosmological parameters by using the ``cosmic inversion'' method in which we directly reconstruct the power spectrum…
Reconstructing the Primordial Spectrum with CMB Temperature and Polarization
Noriyuki Kogo, Misao Sasaki, Jun'ichi Yokoyama
We develop a new method to reconstruct the power spectrum of primordial curvature perturbations, , by using both the temperature and polarization spectra of the cosmic microw…
Reconstructing the Primordial Spectrum from WMAP Data by the Cosmic Inversion Method
Noriyuki Kogo, Makoto Matsumiya, Misao Sasaki +1
We reconstruct the primordial spectrum of the curvature perturbation, , from the observational data of the Wilkinson Microwave Anisotropy Probe (WMAP) by the cosmic inversion…
