Connection among galactic structure, cloud–cloud collision, and star formation activity in the strongly barred galaxy NGC 3627

ABSTRACT :
The star formation efficiency in disk galaxies depends on the galactic structure, particularly low at bars and high at bar ends. This suggests that the galactic structure affects star formation in molecular clouds, especially the properties of molecular cloud collisions. This hypothesis proposes that star formation depends on the collision velocity and surface density of molecular clouds, which are influenced by the galactic structure. In this poster, we present observational results of these dependencies for the barred spiral galaxy NGC 3627 using ALMA and MUSE data.
