We present an initial analysis of a sample of three compact galaxies,
determining mass distribution as a function of radius for each galaxy.
Making qualitative determinations of the radial mass distribution is likely
to provide insight into the mechanisms driving the large-scale galactic
winds observed from the galaxies in the sample. We maintain that the
launching mechanism is not linked to ongoing AGN activity, but rather
perhaps connected to feedback from star formation. We have spatially
resolved the mass distribution in galaxies J0905, J0826, and J1107 and
observed trends supporting previous assumptions that the mass and light
are contained largely within the inner regions of the galaxy. However, we
have also calculated that the mass is perhaps more extended than we had
initially thought, indicating that Vesc may not be on the order of Vout.
This may imply a different launch mechanism than originally
hypothesized, though this mechanism is yet to be determined.
