Spiral Morphology and Radial Migration: Kinematically heating, cooling, and cold

Kathryne J. Daniel, M. E. Wisz, Karen L. Masters +3

Transient spiral arms are known to drive radial redistribution of stars and thus could play a central role in shaping disk galaxies, including modifying, over time, the age, chemic…

The Milky Way Tomography with Subaru Hyper Suprime-Cam: Implications for the past orbit of the Large Magellanic Cloud

Yoshihisa Suzuki, Masashi Chiba, Rosemary F. G. Wyse

We report the discovery of diffuse stellar substructure in the Milky Way's outer halo toward Boötes, unveiled by deep imaging data of the Subaru/Hyper Suprime-Cam. This substructur…

The Milky Way Tomography with Subaru Hyper Suprime-Cam. II. Global halo structure

Yoshihisa Suzuki, Masashi Chiba, Rosemary F. G. Wyse +1

We investigate the structure of the Milky Way's stellar halo within 70 kpc of the Sun using a wide-field photometric catalog obtained from the Hyper Suprime-Cam (HSC) Subaru Strate…

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…

Generalization from Low- to Moderate-Resolution Spectra with Neural Networks for Stellar Parameter Estimation: A Case Study with DESI

Xiaosheng Zhao, Yuan-Sen Ting, Rosemary F. G. Wyse +5

Cross-survey generalization is a critical challenge in stellar spectral analysis, particularly in cases such as transferring from low- to moderate-resolution surveys. We investigat…

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…
