Dark Matter in Draco and Boötes I: Hints of a Core in an Ultra-Faint Dwarf from Simulation-Based Inference
Tri Nguyen, Lina Necib, Ting S. Li +8
The density profiles of dwarf spheroidal galaxies are among the most sensitive probes of dark matter physics, yet extracting them from noisy stellar kinematics remains a fundamenta…
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…
A Long Stellar Stream in M83: Possible Connection Between XUV Disks and Minor Mergers?
Itsuki Ogami, Sakurako Okamoto, Annette M. N. Ferguson +5
We present the confirmation and characterization of a long stream (S-stream) in the southern part of M83. This feature is revealed using deep wide-field photometric data obtained b…
Fuzzy Dark Matter and the Impact of Core--Halo Diversity on Its Particle Mass Constraints
Dafa Wardana, Kohei Hayashi, Masashi Chiba +1
We investigate how diversity in the core--halo mass relation and the inclusion of higher-order velocity moments affect constraints on the fuzzy dark matter particle mass () in…
