Strongly scale-dependent CMB dipolar asymmetry from super-curvature fluctuations
Christian Byrnes, Guillem Domènech, Misao Sasaki +1
We reconsider the observed CMB dipolar asymmetry in the context of open inflation, where a supercurvature mode might survive the bubble nucleation. If such a supercurvature mode mo…
Constraints on mixed dark matter from anomalous strong lens systems
Ayuki Kamada, Kaiki Taro Inoue, Tomo Takahashi
Recently it has been claimed that the warm dark matter (WDM) model cannot at the same time reproduce the observed Lyman-α forests in distant quasar spectra and solve the small-scal…
Effects of electrically charged dark matter on cosmic microwave background anisotropies
Ayuki Kamada, Kazunori Kohri, Tomo Takahashi +1
We examine the possibility that dark matter consists of charged massive particles (CHAMPs) in view of the cosmic microwave background (CMB) anisotropies. The evolution of cosmologi…
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…
Matter Power Spectrum in Hidden Neutrino Interacting Dark Matter Models: A Closer Look at the Collision Term
Tobias Binder, Laura Covi, Ayuki Kamada +3
Dark Matter (DM) models providing possible alternative solutions to the small- scale crisis of standard cosmology are nowadays of growing interest. We consider DM interacting with…
