First Trigonometric Parallax Measurements with the KVN and VERA Array (KaVA)
Nobuyuki Sakai, Daisuke Sakai, Noriyuki Kawaguchi +26
To demonstrate the astrometric capability of the combined Korean VLBI (Very Long Baseline Interferometry) Network (KVN) and VLBI Exploration of Radio Astrometry (VERA) Array (KaVA)…
Molecular absorption lines toward the Galactic ISM detected at 89 GHz with VLBI
Keisuke Nakashima, Hiroshi Imai, Youngjoo Yun
As the first step to explore the Galactic foreground interstellar medium (ISM) with high angular resolution, we investigated the detectability of molecular absorption lines with ve…
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…
A Fast, Hot Wind from a Nuclear Starburst
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137
Galaxies with intense star formation often host multiphase, galaxy-scale winds powered by supernovae and fast stellar winds. These are strong enough to disrupt the star-forming int…
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…
