Scientific paper

We propose to search for kinematic signatures that will prove that a shockwave has passed across regions that appear to be have been triggered into forming massive stars. Our sample selection starts from the massive young stellar objects in our Red MSX Source (RMS) survey that appear to be triggered from their morphology in the Spitzer GLIMPSE survey. These have a bright point source lying in a dark cloud that has strong PAH emission indicating interaction along one side. Recent modeling of magnetically supported clouds hit by an external shock show that a slow-mode wave continues on into the gas behind the dense collapsing clumps and should be observable as a 'smoking gun? of triggering. We propose single-dish observations to narrow down the best targets for future interferometric searches for this kinematic signature.
