Resolving the extended interstellar medium of infrared galaxies II. Fine-structure line emission
We investigate how star formation and active galactic nuclei (AGNs) shape the ionized and neutral interstellar medium in 67 nearby luminous and ultraluminous infrared galaxies from the Great Observatories All-sky LIRG Survey (GOALS). Combining mid-infrared (MIR) spectral mapping from the Spitzer Infrared Spectrograph w...
