The First Star-by-star -body/Hydrodynamics Simulation of Our Galaxy Coupling with a Surrogate Model
Keiya Hirashima, Michiko S. Fujii, Takayuki R. Saitoh +9
A major goal of computational astrophysics is to simulate the Milky Way Galaxy with sufficient resolution down to individual stars. However, the scaling fails due to some small-sca…
Dynamics of tidal spiral arms: Machine learning-assisted identification of equations and application to the Milky Way
Marcel Bernet, Pau Ramos, Teresa Antoja +4
Understanding the spiral arms of the Milky Way (MW) remains a key open question in galactic dynamics. Tidal perturbations, such as the recent passage of the Sagittarius dwarf galax…
Ripples spreading across the Galactic disc. Interplay of direct and indirect effects of the Sagittarius dwarf impact
Tetsuro Asano, Michiko S. Fujii, Junichi Baba +2
Gaia data have revealed vertically asymmetric phase-space structures in the Milky Way (MW) disc, such as phase spirals, indicating vertical oscillations. These oscillations exhibit…
