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…
Constructing a Pristine View of Extended Globular Cluster Structure
Pete B. Kuzma, Miho N. Ishigaki, Takanobu Kirihara +1
Globular Clusters (GCs) displaying extended structures are becoming increasingly ubiquitous in the Milky Way (MW). Despite their low surface brightness, which makes disentangling t…
Estimating Fe and Mg Abundances in the Milky Way Dwarf Galaxies Using Subaru/HSC and DEIMOS
Jihye Hong, Evan N. Kirby, Tiffany M. Tang +5
We investigate the chemical abundance distributions of the Fornax, Sculptor, Ursa Minor, and Draco dwarf galaxies using Subaru/HSC photometric data. The HSC dataset, which includes…
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…
Simultaneous Formation of the Andromeda Giant Southern Stream and the Substructures in the Andromeda Halo
Misa Yamaguchi, Masao Mori, Takanobu Kirihara +4
We investigate a minor merger event in M31 that simultaneously forms the Andromeda Giant Southern Stream (AGSS), Eastern Extent (EE), North-Eastern Shelf (NES), and Western Shel (W…
UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey
Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86
The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…
