Dark Matter Substructure in Lensing Galaxies
Masashi Chiba, Takeo Minezaki, Kaiki T. Inoue +3
To set useful limits on the abundance of small-scale dark matter halos (subhalos) in a galaxy scale, we have carried out mid-infrared imaging and integral-field spectroscopy for a…
Harmonic Inpainting of the Cosmic Microwave Background Sky: Formulation and Error Estimate
Kaiki Taro Inoue, Paolo Cabella, Eiichiro Komatsu
We develop a new interpolation scheme, based on harmonic inpainting, for reconstructing the cosmic microwave background temperature data within the Galaxy mask from the data outsid…
Lens Mapping of Dark Matter Substructure with VSOP-2
Shigenori Ohashi, Masashi Chiba, Kaiki Taro Inoue
Hierarchical clustering models of cold dark matter (CDM) predict that about 5% - 10% of a galaxy-sized halo with mass ~ 10^12 solar masses (M_sun) resides in substructures (CDM sub…
Probing the Origin of the Large-angle CMB Anomalies
Kaiki Taro Inoue
It has been argued that the large-angle cosmic microwave background anisotropy has anomalies at 3-sigma level. We review various proposed ideas to explain the origin of the anomali…
Local Voids as the Origin of Large-angle Cosmic Microwave Background Anomalies: The Effect of a Cosmological Constant
Kaiki Taro Inoue, Joseph Silk
We explore the large angular scale temperature anisotropies in the cosmic microwave background (CMB) due to homogeneous local dust-filled voids in a flat Friedmann-Robertson-Walker…
Gravitational Radiation from Coalescing Supermassive Black Hole Binaries in a Hierarchical Galaxy Formation Model
Motohiro Enoki, Kaiki T. Inoue, Masahiro Nagashima +1
We investigate the expected gravitational wave emission from coalescing supermassive black hole (SMBH) binaries resulting from mergers of their host galaxies. We employ a semi-anal…
