Galactic Archaeology with the Subaru `Ōnohi`ula Prime Focus Spectrograph Strategic Program

Masashi Chiba, Rosemary F. G. Wyse, Evan N. Kirby +48

The recently commissioned Subaru `Ōnohi`ula Prime Focus Spectrograph (PFS) will obtain spectra from nearly 2,400 fibers that cover 1.24 square degrees. The 360 night Subaru Strateg…

Machine Learning Techniques to Distinguish Giant Stars from Dwarf Stars Using Only Photometry -- Pushing Redwards

Keyi Ding, Carrie Filion, Rosemary F. G. Wyse +6

We present our photometric method, which combines Subaru/HSC , g, and i band filters to distinguish giant stars in Local Group galaxies from Milky Way dwarf contamination. T…

The Extended Stellar Distribution in the Outskirts of the Ursa Minor Dwarf Spheroidal Galaxy

Kyosuke S. Sato, Sakurako Okamoto, Masafumi Yagi +7

We discover an extended distribution of main-sequence (MS) stars along the minor axis of the Ursa Minor (UMi) dwarf spheroidal galaxy (dSph). This study is enabled by deep, wide Su…

The Star Formation and Chemical Evolution Histories of Ursa Minor Dwarf Spheroidal Galaxy

Kyosuke S. Sato, Yutaka Komiyama, Sakurako Okamoto +8

We derive the star formation history (SFH) and chemical evolution history (CEH) of the Ursa Minor (UMi) dwarf spheroidal galaxy (dSph). We detect two distinct stellar populations t…

Revealing mass distributions of dwarf spheroidal galaxies in the Subaru-PFS era

Kohei Hayashi, Laszlo Dobos, Carrie Filion +4

The Galactic dwarf spheroidal galaxies (dSphs) provide valuable insight into dark matter (DM) properties and its role in galaxy formation. Their close proximity enables the measure…
