Near-infrared mapping of ARP 299 (IC 694-NGC 3690) - colliding galaxies unveiled

Journal Article · · Astrophys. J.; (United States)
DOI:https://doi.org/10.1086/163756· OSTI ID:5314775
Near-infrared maps and multicolor photometry of the interacting galaxies IC 694 and NGC 3690 which form Arp 299 (= Markarian 171) are presented. These data reveal for the first time the distribution of nuclei and old red stars in a cataclysmically interacting system. The nuclei are considerably offset from the visual centroids of the galaxies but not from the mass centroids. The near-infrared colors of the most active regions are strongly affected by extinction, emission form hot dust, and bremsstrahlung. Near-infrared emission is also identified with secondary regions of star formation, probably resulting from the galaxies interaction. 24 references.
