A Suprime-Cam study of the stellar population of Ursa Major I dwarf spheroidal galaxy
Sakurako Okamoto, Nobuo Arimoto, Yoshihiko Yamada +1
We present deep and wide V, I CCD photometry of Ursa Major I (UMa I) dwarf spheroidal galaxy (dSph) in Local Group. The images of the galaxy were taken by Subaru/Suprime-Cam wide f…
An extended star cluster at the outer edge of the spiral galaxy M33
Rima Stonkute, Vladas Vansevicius, Nobuo Arimoto +6
We report a discovery of an extended globular-like star cluster, M33-EC1, at the outer edge of the spiral galaxy M33. The distance to the cluster is 890 kpc, and it lies at a 12.5…
Radial Age and Metal Abundance Gradients in the Stellar Content of M32
James A. Rose, Nobuo Arimoto, Nelson Caldwell +3
We present long-slit spectroscopy of the elliptical galaxy M32, obtained with the 8-m Subaru telescope at Mauna Kea, the 1.5-m Tillinghast telescope at the F. L. Whipple Observator…
A correlation between light profile and [Mg/Fe] abundance ratio in early-type galaxies
Alexandre Vazdekis, Ignacio Trujillo, Yoshihiko Yamada
We explore possible correlations between light profile shapes, as parameterized by the Sersic index or the concentration index C_re(1/3), and relevant stellar population parameters…
