PHANGS: Physics at High Angular resolution in Nearby GalaxieS



Hsi-An Pan

Star formation in galaxies is determined by the efficiency of the conversion of gas to stars and stellar feedback that shapes the reservoir of gas for future star formation. I will introduce the ALMA Large Program PHANGS (Physics at High ANgular resolution in Nearby GalaxieS) in this talk. The goal of PHANGS is to study the link between the small-scale (~100 pc) physics of star formation and their host-galaxy properties. This is done by sampling the full time sequence of star formation process in 74 local galaxies, from molecular gas (ALMA), to HII regions (VLT/MUSE, MPG2.2-m, and du Pont telescopes), and to young stellar clusters (HST). I will show some analysis efforts made by the team and data products soon to be released.
