astro-ph.GA2026

A differentiable hydrodynamical approach to the Milky Way bar pattern speed with CO longitude--velocity data

Junichi Baba, Kohei Hattori

We present a differentiable hydrodynamical framework for modeling barred gas flow in the Milky Way and constraining broad low-loss regions in bar-pattern-speed parameter space from…

Dynamical clock of the Helmi stream -- Analysis of the clumping of stars in the orbital frequency-space

Kohei Hattori

Reconstructing the assembly history of the Milky Way requires precise constraints on the dynamical age of its merger remnants -- the time elapsed since a progenitor satellite was d…

HR-GO II: chemical abundances of low-E retrograde dynamically-tagged-groups: Revealing Thamnos as a very metal-poor substructure

Renjing Xie, Zhen Yuan, Haining Li +12

Milky Way halo substructures identified in dynamical space are known to suffer from contamination from the Milky Way in-situ stars, which makes their accreted origins uncertain. We…
