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

Abstract

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.
