Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (<kpc) and global galaxy environment. We present first results from two large observing programs on ALMA and VLT/MUSE, mapping cloud scales (1arcsec = 47pc) in both molecular gas and star forming tracers across 90 kpc^2 of the central disk of NGC 628 to probe the physics of star formation. Systematic spatial offsets between molecular clouds and HII regions illustrate the time evolution of star-forming regions. Using uniform sampling of both maps on 50-500 pc scales, we infer molecular gas depletion times of 1-3 Gyr, but also find the increase of scatter in the star formation relation on small scales is consistent with gas and HII regions being only weakly correlated at the cloud (50 pc) scale. This implies a short overlap phase for molecular clouds and HII regions, which we test by directly matching our catalog of 1502 HII regions and 738 GMCs. We uncover only 74 objects in the overlap phase, and we find depletion times >1 Gyr, significantly longer than previously reported for individual star-forming clouds in the Milky Way. Finally, we find no clear trends that relate variations in the depletion time observed on 500 pc scales to physical drivers (metallicity, molecular and stellar mass surface density, molecular gas boundedness) on 50 pc scales.
Star formation induced by a spiral shock wave, which in turn is generated by a spiral density wave, produces an azimuthal age gradient across the spiral arm, which has opposite signs on either side of the corotational resonance. An analysis of the sp
We present the first spatially resolved (~0.5 kpc) measurements of the molecular gas depletion time $tau_{depl}$ across the disk of the interacting spiral galaxy NGC,2276, a system with an asymmetric morphology in various SFR tracers. To estimate $ta
We present a detailed clustering analysis of the young stellar population across the star-forming ring galaxy NGC 6503, based on the deep HST photometry obtained with the Legacy ExtraGalactic UV Survey (LEGUS). We apply a contour-based map analysis t
Relations between star formation rates along the spiral arms and the velocities of gas inflow into the arms in grand-design galaxy NGC 628 were studied. We found that the radial distribution of average star formation rate in individual star formation
We present a spatially resolved study of the relation between dust and metallicity in the nearby spiral galaxies M101 (NGC 5457) and NGC 628 (M74). We explore the relation between the chemical abundances of their gas and stars with their dust content
