The complex evolutionary paths of local infrared bright galaxies: a high-angular resolution mid-infrared view

Abstract:

We investigate the evolutionary connection between local infrared (IR)-bright galaxies (logLIR ≥11.4 Lʘ) and quasars. We use high-angular resolution (∼0.3–0.4 arcsec∼few hundred parsecs) 8–13µm ground-based spectroscopy to disentangle the active galactic nuclei (AGN) id-IR properties from those of star formation. The comparison between the nuclear 11.3µm polycyclic aromatic hydrocarbon feature emission and that measured with Spitzer/Spitzer Infrared Spectrograph indicates that the star format...
