A Multi-Scale Approach to Understand Outflows from High-Mass Protostars

The nature and role of jets and outflows in the formation of high-mass stars is still poorly understood. This poster summarizes the different projects our research group undertook to investigate these phenomena during the last 4 years. We have used the Very Large Array (VLA), the Submillimeter Array (SMA), and the Arecibo Telescope to study the continuum and line emission associated with mass ejecta from high-mass young stellar objects (YSOs). Moreover, our approach allows us to cover a wide range of scales, from au- (e.g., water masers) to pc-scale objects (e.g., molecular outflows), and evolutionary stages, from cold molecular cores to ultra compact H II regions. The diverse techniques, instruments, and wavelengths implemented in our research allow us to investigate the connection of the ionized and molecular emission at all scales and give us a comprehensive view of the birth of high-mass stars. These works are part of the NSF funded project JOURNEY (Jets and OUtflows Revealing the Nature and Evolution of massive YSOs, grants AST-1814011 and AST-1814063).
