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…
Circular Polarization from Gamma-ray Burst Afterglows
Makoto Matsumiya, Kunihito Ioka
We investigate the circular polarization (CP) from Gamma-Ray Burst (GRB) afterglows. We show that a tangled magnetic field cannot generate CP without an ordered magnetic field beca…
Cosmic Inversion II --An iterative method for reproducing the primordial spectrum from the CMB data--
Makoto Matsumiya, Misao Sasaki, Jun'ichi Yokoyama
Pursuing the original idea proposed in our previous paper (Paper I), we improve the method to determine the shape of the initial curvature perturbation spectrum from the CMB…
Cosmic Inversion: Reconstructing primordial spectrum from CMB anisotropy
Makoto Matsumiya, Misao Sasaki, Jun'ichi Yokoyama
We investigate the possibility of reconstructing the initial spectrum of density fluctuations from the cosmic microwave background (CMB) anisotropy. As a first step toward this pro…
