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…

Axisymmetric Jeans modelling systematically overestimates the circular speed in the inner Milky Way

Tomoki Yamaguchi, Junichi Baba

We quantify systematic biases in rotation curves inferred from steady, axisymmetric Jeans modelling when the underlying stellar velocity field is non-axisymmetric. Using a high-res…

Bar-Informed Kinematic-Distance Mapping of Molecular Gas in the Inner Milky Way

Junichi Baba

We present a bar-informed kinematic-distance (BIKD) method to reconstruct face-on molecular-gas maps of the inner Milky Way from PPV data, relaxing the standard assumption of axisy…

Kinematic-Distance Biases in the Inner Milky Way from a Stellar-Dynamically Constrained Bar

Junichi Baba

We quantify how bar-driven non-circular motions bias Milky-Way gas maps inferred with the kinematic-distance (KD) method. KD reconstructions of H\,\textsc{i} and CO surveys assume…
