Title : Evolutionary Description of Giant Molecular Cloud Mass Functions on Galactic Disks
Abstract: e formulate the time-evolution equation for giant molecular cloud (GMC) mass functions in galactic disks. The computed time-evolutions show that the cloud-cloud collision effect is only limited in the massive end of mass function, and that almost 100 percent of the gas dispersed by stellar feed back is transformed into a newer generation GMCs in inter-arm regions whereas only about 40 percent in arm regions. Our results suggest that measuring the power-law slope of GMC mass functions can be a powerful method to constrain GMC formation and dispersal timescales and gas resurrection processes in various galactic environments.
