Fabry-Perot Imaging Spectroscopy of Interacting and Merging Galaxies: NGC 3690 and NGC 6240

We present 2 micrometer spectroscopic images in the H2 nu=1-0 S(1) line, the Br gamma recombination line of atomic hydrogen, and the neighboring continuum of the central regions of the galaxies NGC 3690/IC 694 and NGC 6240. Based on the morphology of these images we assess the contributions of star...

Description
Summary:We present 2 micrometer spectroscopic images in the H2 nu=1-0 S(1) line, the Br gamma recombination line of atomic hydrogen, and the neighboring continuum of the central regions of the galaxies NGC 3690/IC 694 and NGC 6240. Based on the morphology of these images we assess the contributions of star formation, colliding disks, and nuclear activity to the line emission. Sponsored in part by NASA Grant no. NAGW-1711. Presented at the Conference on Astrophysics with Infrared Arrays held in Tucson, AZ in Feb 1990. Published in Astronomical Society of the Pacific Conference Series, v14, Astrophysics with Infrared Arrays, p63-66, 1990.
