Electromagnetic Properties of the Early Universe
Keitaro Takahashi, Kiyotomo Ichiki, Naoshi Sugiyama
Detailed physical processes of magnetic field generation from density fluctuations in the pre-recombination era are studied. Solving Maxwell equations and the generalized Ohm's law…
Laser-interferometric Detectors for Gravitational Wave Background at 100 MHz : Detector Design and Sensitivity
Atsushi Nishizawa, Seiji Kawamura, Tomotada Akutsu +8
Recently, observational searches for gravitational wave background (GWB) have developed and given direct and indirect constraints on the energy density of GWB in a broad range of f…
Magnetic Field Spectrum at Cosmological Recombination
Kiyotomo Ichiki, Keitaro Takahashi, Naoshi Sugiyama +2
A generation of magnetic fields from cosmological density perturbations is investigated. In the primordial plasma before cosmological recombination, all of the materials except dar…
