G. Abstract Arp 299C is a 5 X 10^10^ L_sun_ infrared source in the merging galaxy system Arp 299. It is the most luminous object known that is not obviously associated with a galaxy nucleus. Our data show that the 8-13 micron spectrum of Arp 299C has a strong [Ne II] emission line and emission features like those of polycyclic aromatic hydrocarbon (PAH) molecules. These emission features are characteristic of H II regions associated with a burst of star formation. We did not detect any high- excitation ionic lines characteristic of an active galactic nucleus (AGN), nor a deep silicate absorption feature that might indicate a hidden compact nucleus. We deduce that Arp 299C is powered by an intense burst of star formation.
