Title: Spatially Resolved Kinematics and Excitation of Ionized Gas in Starburst Galaxies

Abstract: We propose to obtain spectroscopic datacubes of a sample of 11 infrared-luminous galaxies. The targets are chosen from the IRAS Bright Galaxy Sample (BGS), all of which show evidence for an ongoing starburst. Additionally, many of these galaxies are advanced mergers, or show clear signs of strong interactions. The kinematics of these galaxies are complicated, and many of them have significant off-nuclear star formation activity. We plan to use the DensePak Fiber Array on the WIYN 3.5m telescope to obtain spectra across the entire face of each galaxy system. The strengths, distributions, profiles, and velocities of the lines will allow us to study the kinematics and excitation of the ionized and heated gas in these galaxies. Emission line equivalent widths and line ratios will further allow us to apply diagnostics to investigate the star formation age, the abundances, and the ionization parameter as a function of position throughout each galaxy. These data in combination with similar data obtained for southern galaxies will contribute to understanding of interacting galaxies, galaxy evolution, and star formation.
