Abstract

In this paper, we compare the radio emission at 1.4 GHz with optical outflowsignatures of edgeon galaxies. We report observations of six edge-on star-forming galaxies in the Sydney-AAO Multiobject Integral-field spectrograph Galaxy Survey with 1.4 GHz luminosities > 1 x 10(21) WHz(-1). Extended minor axis optical emission is detected with enhanced [N II]/II alpha line ratios and velocity dispersions consistent with galactic winds in three of six galaxies. These galaxies may host outflows driven by a combination of thermal and cosmic ray processes. We find that galaxies with the strongest wind signatures have extended radio morphologies. Our results form a baseline for understanding the driving mechanisms of galactic winds.
