Abstract We plan to test two scenarios of massive star formation -- disc accretion or coalescence of low mass stars -- from observations of massive young stellar objects (MYSOs). The first step is to identify those high mass objects (M> 8 MSun) that are associated with near-infrared outflows. The second step, consists on the measurement of the parameters of the outflows at their launching points with enough spatial and spectral resolution to decide if they are originated by the same type of phenomena that occurs on low mass counterparts or if they are launched by winds produced by the accreting discs. This would require wavelengths longer than mid-IR in order to overcome the extinction of the dense and embedded environments of massive star formation.The submillimeter window could provide some insight of both the real morphology of the large scale outflows using single dish observations (APEX) or even go closer on the circumstellar region of the MYSOs using interferometric techniques (ALMA). In order to learn the techniques required to perform these follow-up studies, this project aims to use single-dish and interferometer submillimeter data to study massive molecular outflows associated with MYSOs. The sources were previously selected from the ATLASGAL survey and observed in mid-J CO transitions using APEX and other single-dish radio telescopes. (AU) | |
