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…
Searching optimal scales for reconstructing cosmological initial conditions using convolutional neural networks
Koichiro Nakashima, Kiyotomo Ichiki, Atsushi J. Nishizawa +1
Reconstructing the initial density field of the Universe from the late-time matter distribution is a nontrivial task with implications for understanding structure formation in cosm…
Survival of Gas in Subhalos and Its Impact on the 21 cm Forest Signals: Insights from Hydrodynamic Simulations
Genki Naruse, Kenji Hasegawa, Kenji Kadota +2
Understanding the survival of gas within subhalos under various astrophysical processes is crucial for elucidating cosmic structure formation and evolution. We study the resilience…
First Season MWA Phase II EoR Power Spectrum Results at Redshift 7
W. Li, J. C. Pober, N. Barry +44
The compact configuration of Phase II of the Murchison Widefield Array (MWA) consists of both a redundant subarray and pseudo-random baselines, offering unique opportunities to per…
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)…
