Connection between Non-Axisymmetric Structures and Neutral Gas Distribution in Disk Galaxies

Ze-Zhong Liang, Jing Wang, Hua Gao +2

Non-axisymmetric structures, such as bars and spiral arms, are known to concentrate molecular gas and star formation in galaxy centers, actively building up the pseudo-bulges. Howe…
