Exploring the Primordial Power Spectrum with Dark-Age 21 cm fluctuations
Fumiya Okamatsu, Tomo Takahashi, Shuichiro Yokoyama
We investigate the potential of future observations of the Dark Ages 21 cm power spectrum to probe the scale dependence of the primordial power spectrum and distinguish between inf…
Casimir-Induced Quintessence in Dark Dimension
Tomoki Katayama, Hiroki Matsui, Yuri Michinobu +3
We investigate a concrete realization of the Dark Dimension scenario, where a single large extra dimension is set at sub-millimeter scales. In this framework, the Casimir energy of…
Detectability and Template Distinguishability of the Dark Ages 21 cm Global Signal with Wide and Sparse Frequency Coverage
Shintaro Yoshiura, Fumiya Okamatsu, Tomo Takahashi
The Dark Ages 21cm signal, observed at frequencies below 50 MHz, can serve as a powerful probe of cosmology, as the standard cosmological model predicts a well-defined 21cm spectra…
