Dark age consistency in the 21cm global signal
Fumiya Okamatsu, Teppie Minoda, Tomo Takahashi +2
We propose a new observable for the 21cm global signal during the dark ages, the dark-age consistency ratio, which is motivated from the fact that the shape of the functional form…
EDGES and JWST with 21cm global signal emulator
Shintaro Yoshiura, Teppei Minoda, Tomo Takahashi
The 21cm global signal is an important probe to reveal the properties of the first astrophysical objects and the processes of the structure formation from which one can constrain a…
Impact of the primordial fluctuation power spectrum on the reionization history
Teppei Minoda, Shintaro Yoshiura, Tomo Takahashi
We argue that observations of the reionization history can be used as a probe of primordial density fluctuations, particularly on small scales. Although the primordial curvature pe…
Probing the primordial Universe with 21-cm line from cosmic dawn/epoch of reionization
Teppei Minoda, Shohei Saga, Tomo Takahashi +4
In the most distant reaches of the Universe, the 21-cm hyperfine transition in neutral hydrogen provides one of the only available tracers of large-scale structure. A number of ins…
