Scientific paper

Infrared imagery and photometry of the interacting galaxy system Arp 299 are presented. In the central region of NGC 3690 there are two 2.2 micron sources; one of these (component B2) coincides with the apparent visible nucleus, while the other (component B1) coincides with the 6 cm and 10 micron sources. No evidence at 2.2 micron is seen for a compact AGN in IC 694 (component A). Approximately 75 percent of the 12-25 micron power from Arp 299 comes from three regions each smaller than 600 pc in diameter centered on components A, B1, and C, making the distribution of mid-infrared emission more concentrated than the distribution of starlight.
