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…
JFlow: Model-Independent Spherical Jeans Analysis using Equivariant Continuous Normalizing Flows
Sung Hak Lim, Kohei Hayashi, Shun'ichi Horigome +2
The kinematics of stars in dwarf spheroidal galaxies have been studied to understand the structure of dark matter halos. However, the kinematic information of these stars is often…
Stringent Constraints on Self-Interacting Dark Matter Using Milky-Way Satellite Galaxies Kinematics
Shin'ichiro Ando, Kohei Hayashi, Shunichi Horigome +2
Self-interacting dark matter (SIDM) has been proposed to address small-scale challenges faced by the cold dark matter (CDM) paradigm, such as the diverse density profiles observed…
SASHIMI-SIDM: Semi-analytical subhalo modelling for self-interacting dark matter at sub-galactic scales
Shin'ichiro Ando, Shunichi Horigome, Ethan O. Nadler +2
We combine the semi-analytical structure formation model, SASHIMI, which predicts subhalo populations in collisionless, cold dark matter (CDM), with a parametric model that maps CD…
Cosmological prior for the -factor estimation of dwarf spheroidal galaxies
Shun'ichi Horigome, Kohei Hayashi, Shin'ichiro Ando
Dark matter halos of dwarf spheroidal galaxies (dSphs) play important roles in dark matter detection. Generally we estimate the halo profile using a kinematical equation of dSphs b…
