A lower bound on primordial power spectrum from halo substructure
Shin'ichiro Ando, Nagisa Hiroshima, Koji Ishiwata +1
We investigate how the primordial curvature perturbation of a certain wavelength scale affects the halo and subhalo structure. Primordial power spectrum considered in this paper fe…
Probing warm and mixed dark matter models using lensing shift power spectrum
Kaiki Taro Inoue, Takumi Shinohara, Teruaki Suyama +1
We argue that the lensing power spectrum of astrometric shift (lensing shift power spectrum) is a powerful tool of the clustering property of dark matter on subgalactic scales. Fir…
Generalized early dark energy and its cosmological consequences
Tatsuki Kodama, Takumi Shinohara, Tomo Takahashi
We investigate cosmological consequences of a generalized early dark energy (EDE) model where a scalar field behaves as dark energy at various cosmological epochs for a broad range…
