Do giant molecular clouds care about the galactic structure?

Fujimoto, Yusuke; Tasker, Elizabeth J.; Wakayama, Mariko; Habe, Asao

Description

We investigate the impact of galactic environment on the properties of simulated giant molecular clouds (GMCs) formed in an M83-type barred spiral galaxy. Our simulation uses a rotating stellar potential to create the grand design features and resolves down to 1.5 pc. From the comparison of clouds found in the bar, spiral and disc regions, we find that the typical GMC is environment independent, with a mass of 5 × 105 M⊙ and radius 11 pc. However, the fraction of clouds in the property...[Show more]
