Dark and stellar matter in strong lensing galaxies from a joint lensing and stellar dynamics
Takashi Hamana, Youichi Ohyama, Masashi Chiba +1
We present Subaru spectroscopy of the early-type lensing galaxies in the lens systems HST14113+5211 (z=0.464) and B2045+265 (z=0.868), being aimed at measuring the velocity dispers…
Galaxy Formation: One Star at a Time. New Information from the Kinematics of Field Stars in the Galaxy
Timothy C. Beers, Masashi Chiba
We present a review of recent studies of the formation and evolution of the Milky Way galaxy, in particular based on large samples of non-kinematically selected stars with availabl…
Stellar Kinematics of the Spiral Structure in the Solar Neighborhood
Taihei Yano, Masashi Chiba, Naoteru Gouda
We present a method, based on the kinematic analysis of the Galactic disk stars, to clarify whether the internal motions of the stellar system in spiral arms follow those expected…
Numerical simulation of large-scale magnetic-field evolution in spiral galaxies
K. Otmianowska-Mazur, M. Chiba
The evolution of large-scale magnetic fields in disk galaxies is investigated numerically. The gasdynamical simulations in a disk perturbed by spiral or bar potential are incorpora…
Protogalactic evolution and magnetic fields
Harald Lesch, Masashi Chiba
We show that the relatively strong magnetic fields (G) in high redshift objects can be explained by the combined action of an evolving protogalactic fluctuation and electr…
