ENERGETIC OUTFLOWS IN LUMINOUS INFRARED GALAXIES

We have obtained wide-field Fabry-Perot observations of the starburst galaxies M82 and NGC 253 in several strong emission lines (Halpha, [NI I]lambda6583, [OIII]lambda5007, Hbeta). These remarkable data reveal t hat the minor axis optical filaments, presumably associated with ''gal actic winds'', are highly energetic (approximately 10(55) ergs) and di splay complex behavior. We have also obtained deep B, R, I, and Halpha imagery of M82, in order to more carefully examine spatial details of the filamentary structure. These data provide both detailed kinematic information and emission-line diagnostics for modeling the outflow.
