Constraints on the Primordial Magnetic Field from
Dai G. Yamazaki, Kiyotomo Ichiki, Toshitaka Kajino +1
A primordial magnetic field (PMF) can affect the evolution of density field fluctuations in the early universe.In this paper we constrain the PMF amplitude and power spectral…
Effects of a Primordial Magnetic Field on Low and High Multipoles of the CMB
Dai G. Yamazaki, Kiyotomo Ichiki, Toshitaka Kajino +1
The existence of a primordial magnetic field (PMF) would affect both the temperature and polarization anisotropies of the cosmic microwave background (CMB). It also provides a plau…
A Simultaneous Solution to the ^6Li and ^7Li Big Bang Nucleosynthesis Problems from a Long-Lived Negatively-Charged Leptonic Particle
Motohiko Kusakabe, Toshitaka Kajino, Richard N. Boyd +2
The Li abundance observed in metal poor halo stars exhibits a plateau similar to that for Li suggesting a primordial origin. However, the observed abundance of Li is a…
Primordial magnetic field constrained from CMB anisotropies,and its generation and evolution before, during and after the BBN
Dai G. Yamazaki, Kiyotomo Ichiki, Toshitaka Kajino +1
The primordial magnetic field (PMF) can strongly affect the cosmic microwave background (CMB) power spectrum and the formation of large scale structure. In this presentation, we ca…
