Testing multi-field inflation with LiteBIRD
Ryusuke Jinno, Kazunori Kohri, Takeo Moroi +2
We investigate expected constraints on the primordial tensor power spectrum from the future cosmic microwave background polarization experiment LiteBIRD as a test of multi-field in…
Signals of Axion Like Dark Matter in Time Dependent Polarization of Light
So Chigusa, Takeo Moroi, Kazunori Nakayama
We consider the search for axion-like particles (ALPs) by using time series data of the polarization angle of the light. If the condensation of an ALP plays the role of dark matter…
Can decaying particle explain cosmic infrared background excess?
Kazunori Kohri, Takeo Moroi, Kazunori Nakayama
Recently the CIBER experiment measured the diffuse cosmic infrared background (CIB) flux and claimed an excess compared with integrated emission from galaxies. We show that the CIB…
Studying Inflation with Future Space-Based Gravitational Wave Detectors
Ryusuke Jinno, Takeo Moroi, Tomo Takahashi
Motivated by recent progress in our understanding of the -mode polarization of cosmic microwave background (CMB), which provides important information about the inflationary gra…
Probing dark radiation with inflationary gravitational waves
Ryusuke Jinno, Takeo Moroi, Kazunori Nakayama
Recent cosmological observations indicate the existence of extra light species, i.e., dark radiation. In this paper we show that signatures of the dark radiation are imprinted in t…
Cosmic Gamma-ray from Inverse Compton Process in Unstable Dark Matter Scenario
Koji Ishiwata, Shigeki Matsumoto, Takeo Moroi
Motivated by the PAMELA anomaly in the fluxes of cosmic-ray electron and positron, we study the cosmic gamma-ray induced by the inverse Compton (IC) scattering process in unstable…
