Faraday Rotation Effect of Intracluster Magnetic Field on Cosmic Microwave Background Polarization
Masahiro Takada, Hiroshi Ohno, Naoshi Sugiyama
The observed magnetic field of microgauss strength in clusters of galaxies should induce the Faraday rotation effect on the linearly polarized cosmic microwave background (CMB) rad…
On the Cross-Correlation between Dark Matter Distribution and Secondary CMB Anisotropies by Ionized Intergalactic Medium
Masahiro Takada, Naoshi Sugiyama
We investigate a cross-correlation between the weak gravitational lensing field of the large-scale structure, , and the secondary temperature fluctuation field, , of cosmic m…
Implication of Omega_m through the Morphological Analysis of Weak Lensing Fields
Jun'ichi Sato, Masahiro Takada, Y. P. Jing +1
We apply the morphological descriptions of two-dimensional contour map, the so-called Minkowski functionals (the area fraction, circumference, and Euler characteristics), to the co…
Lensing-induced Non-Gaussian Signatures in the Cosmic Microwave Background
Masahiro Takada
We propose a new method for extracting the non-Gaussian signatures on the isotemperature statistics in the cosmic microwave background (CMB) sky, which is induced by the gravitatio…
