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…
Bar-driven Streaming Motions Mimic a Massive Bulge in the Inner Milky Way
Junichi Baba
The circular speed curve of the Milky Way provides a key constraint on its mass distribution, reflecting the axisymmetric component of the gravitational potential. This is especial…
Influence of Bar Formation on Star Formation Segregation and Stellar Migration: Implications for Variations in the Age Distribution of Milky Way Disk Stars
Junichi Baba
We present a chemo-dynamical -body/hydrodynamic simulation of an isolated Milky Way-like galaxy to investigate how bar formation influences star formation rates, stellar migrati…
Multi-phase Nature of a Radiation-Driven Fountain with Nuclear Starburst in a Low-mass Active Galactic Nucleus
Keiichi Wada, Marc Schartmann, Rowin Meijerink
The structures and dynamics of molecular, atomic, and ionized gases are studied around a low-luminosity active galactic nucleus (AGN) with a small () black ho…
