Constraining the EoR model parameters with the 21cm bispectrum
Hayato Shimabukuro, Shintaro Yoshiura, Keitaro Takahashi +2
We perform a Fisher analysis to estimate the expected constraints on the Epoch of Reionization (EoR) model parameters (i.e., minimum virial temperature, the ionizing efficiency and…
Japanese Cosmic Dawn/Epoch of Reionization Science with the Square Kilometre Array
Kenji Hasegawa, Shinsuke Asaba, Kiyotomo Ichiki +10
Cosmic reionization is known to be a major phase transition of the gas in the Universe. Since astronomical objects formed in the early Universe, such as the first stars, galaxies a…
Cosmology with the Square Kilometre Array by SKA-Japan
Daisuke Yamauchi, Kiyotomo Ichiki, Kazunori Kohri +8
In the past several decades, the standard cosmological model has been established and its parameters have been measured to a high precision, while there are still many of the funda…
Constraining the Contribution of Galaxies and Active Galactic Nuclei to Cosmic Reionization
Shintaro Yoshiura, Kenji Hasegawa, Kiyotomo Ichiki +3
Understanding the detailed process of cosmic reionization is one of the remaining problems in astrophysics and cosmology. Here we construct a model of cosmic reionization that incl…
Expected constraints on models of the epoch of reionization with the variance and skewness in redshifted 21cm-line fluctuations
Kenji Kubota, Shintaro Yoshiura, Hayato Shimabukuro +1
Redshifted 21cm-line signal from neutral hydrogens in the intergalactic medium (IGM) gives a direct probe of the epoch of reionization (EoR). In this paper, we investigate the pote…
Studying topological structure in the epoch of reionization with 3D-Minkowski functionals of 21cm line fluctuations
Shintaro Yoshiura, Hayato Shimabukuro, Keitaro Takahashi +1
The brightness temperature of the redshifted 21cm line brings rich information on the Inter Galactic Medium (IGM) from the Cosmic Dawn and Epoch of Reionization (EoR). While the po…
