Observing Galaxy Evolution
The redshift range z=1-3 corresponds to the era when the co-moving star formation density of the Universe peaked. Spectroscopic surveys have shown that galaxies at these early times were drastically different from those locally, with massive, gas-rich galaxies undergoing rapid star formation in globally unstable disks, and the Hubble sequence not yet in place. To understand the physical processes driving their star formation, we must spatially resolve the star formation and gas dynamics within the ISM of high-redshift galaxies on scales of individual star forming regions. In this talk, I will review the latest multi-wavelength observations which aim to measure the interaction between star formation and gas dynamics within the ISM of hundreds of high-redshift galaxies on scales that range from a few kilo-parsecs to just 100 parsecs. The goal of the observations is to constrain how the star formation assembled the bulk of the stellar mass in today’s massive galaxies and how secular processes crystallised the Hubble sequence around z~1.
