Analytic and numerical study of dark matter halos in the Horndeski theory

Kohei Onoda, Shun Arai, Daisuke Yamauchi +3

The models of modified gravity that can explain the late-time accelerated expansion of the Universe must pass the local tests of gravity, introducing a screening mechanism so that…

Inferring population III star properties from the 21-cm global signal

Sho Ukai, Hayato Shimabukuro, Kenji Hasegawa +1

Investigating the properties of the first stars in the universe, known as Population III (Pop~III) stars, is essential, yet it remains an open question. One way to explore these st…

Detectability of 21cm-signal during the Epoch of Reionization with 21cm-Lyman-α emitter cross-correlation. II. Foreground contamination

S. Yoshiura, J. L. B. Line, K. Kubota +2

Cross-correlation between the redshifted 21 cm signal and Lyman-α emitters (LAEs) is powerful tool to probe the Epoch of Reionization (EoR). Although the cross-power spectrum (PS)…
