Characterizing the GD-1 Stream with DESI DR2 Data: Thin Stream and Hot Cocoon
Emma Jarvis, Ting S. Li, Sergey E. Koposov +54
GD-1 is among the longest, coldest stellar streams in the Milky Way, making it an ideal target for probing dark matter substructure through dynamical heating. We present a catalog…
The velocity field of our Milky Way outer stellar halo based on DESI DR2
Songting Li, Wenting Wang, Sergey E. Koposov +53
Using 64,000 halo K giants from Dark Energy Spectroscopic Instrument (DESI) second Data Release (DR2), we decompose the Milky Way (MW) stellar halo between 3 and 160 kpc into metal…
Exploring faint white dwarfs and the luminosity function with Subaru HSC and SDSS in Stripe 82
Tian Qiu, Masahiro Takada, Naoki Yasuda +4
We present 5,080 white dwarf (WD) candidates selected from stars matching between the multi-band imaging datasets of the Subaru Hyper Suprime-Cam (HSC) Survey and the Sloan Digital…
The Milky Way Tomography with Subaru Hyper Suprime-Cam. I. Halo substructures
Yoshihisa Suzuki, Masashi Chiba, Yutaka Komiyama +7
We analyze the photometric data in the Wide layer of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) over deg to uncover new halo substructures beyond t…
Study of structural parameters and systemic proper motion of Sextans dwarf spheroidal galaxy with Subaru Hyper Suprime-Cam data
Akira Tokiwa, Masahiro Takada, Tian Qiu +4
We use the Subaru Hyper Suprime-Cam (HSC) data to study structural parameters and systemic proper motion of the Sextans dwarf spheroidal galaxy at the heliocentric distance of 86 k…
A comparative study of satellite galaxies in Milky Way-like galaxies from HSC, DECaLS and SDSS
Wenting Wang, Masahiro Takada, Xiangchong Li +10
We conduct a comprehensive and statistical study of the luminosity functions (LFs) for satellite galaxies, by counting photometric galaxies from HSC, DECaLS and SDSS around isolate…
Proper motion measurements for stars up to kpc with Subaru HSC and SDSS Stripe 82
Tian Qiu, Wenting Wang, Masahiro Takada +6
We present proper motion measurements for more than million main-sequence stars, by comparing astrometric positions of matched stars between the multi-band imaging datasets…
