SUMMARY:Connecting star formation to galactic dynamics - Florent Renaud (U

DESCRIPTION:Recent improvements of observational and numerical techniques 
 have \npermitted to unveil the wide diversity of star forming clouds\, in 
 the \nMilky Way but also in other nearby galaxies. The variety in the \nmo
 rphology and dynamics of these clouds\, as a function of their galactic \n
 environment\, strongly suggests a complex interplay between global \n(kpc-
 scale) and local (pc-scale) processes\, that remains to be fully \nunderst
 ood. The coupling between large-scale structures\, turbulence\, \nself-gra
 vity\, magnetic fields and feedback makes this problem one of the \nmost c
 hallenging of modern astrophysics. Using a set of \n(sub)parsec-resolution
  simulations of galaxies including local spirals\, \nmergers and high reds
 hift disks\, I will illustrate the diversity of star \nformation in simula
 tions and compare to what is observed. I will \nemphasise the role of the 
 variation of parameters within a single disk \ngalaxy and then explore the
  differences from galaxy to galaxy. I will \npropose a new theory on the t
 riggering of star formation in local \nmergers and discuss its implication
 s on the non-universality of the \nstellar initial mass function. I will c
 onclude by drawing a connection \nto galaxies at higher redshifts.\n
