We present the discovery of compact, obscured star formation in galaxies at z similar to 0.6 that exhibit greater than or similar to 1000 km s(-1) outflows. Using optical morphologies from the Hubble Space Telescope and infrared photometry from the Wide-field Infrared Survey Explorer, we estimate star formation rate (SFR) surface densities that approach Sigma(SFR) approximate to 3000 M-circle dot yr(-1) kpc(-2), comparable to the Eddington limit from radiation pressure on dust grains. We argue that feedback associated with a compact starburst in the form of radiation pressure from massive stars and ram pressure from supernovae and stellar winds is sufficient to produce the high-velocity outflows we observe, without the need to invoke feedback from an active galactic nucleus.
