Origin of structural and kinematical properties of the Small Magellanic Cloud
Kenji Bekki, Masashi Chiba
We investigate structural, kinematical, and chemical properties of stars and gas in the Small Magellanic Cloud (SMC) interacting with the Large Magellanic Cloud (LMC) and the Galax…
Formation of the Small Magellanic Cloud: ancient major merger as a solution to the kinematical differences between old stars and HI gas
Kenji Bekki, Masashi Chiba
Recent observations of the Small Magellanic Cloud (SMC) have revealed that the HI gas shows a significant amount of rotation (V_c 60 km/s), while no or little rotation is evident f…
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…
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…
