Environmental dependence of star formation induced by cloud collisions in a barred galaxy

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


Cloud collision has been proposed as a way to link the small-scale star formation process with the observed global relation between the surface star formation rate and gas surface density.We suggest that this model can be improved further by allowing the productivity of such collisions to depend on the relative velocity of the two clouds. Our adjustment implements a simple step function that results in the most successful collisions being at the observed velocities for triggered star formation....[Show more]
