Investigating massive star formation with HII regions

SIGNALS is the largest, most complete, homogeneous dataset of extragalactic HII regions to date. Using the imaging spectrograph SITELLE at the Canada-France-Hawaii Telescope, the team will learn about the interplay between star formation and interstellar gas in the local universe.
