Sub-kpc scale gas density histograms of the nearby barred spiral galaxy M83: Multi-component molecular gas structure reflecting the galactic environment
Ren Matsusaka, Toshihiro Handa, Fumi Egusa +8
We investigate the sub-kiloparsec (sub-kpc) molecular ISM structure and its relation to the galactic environment and star formation in the barred spiral galaxy M83 (NGC 5236). We e…

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…
