Jets and Outflows from High-Mass Protostars from a Multi-Scale and Multi-Wavelength Point of View

Even though high-mass stars (M_* > 8 Msun) are of great importance in Astrophysics, many questions remain unanswered regarding their formation. One proposed model is a scaled-up version of the core accretion process, similar to the formation of low-mass stars. In this scenario, bipolar jets and outflows play a key, yet poorly understood role in shedding excess angular momentum and regulating the star formation process. A large variety of physical processes occur during the launching of flows, including complex interactions with the surrounding medium. In the last two decades, a variety of shock tracers ranging from radio wavelengths to the high energy regime have been observed from outflows on scales from a few au to several pc. Thus, observations with different instruments and over a wide frequency range are necessary to fully grasp the nature and role of jets and outflows during high-mass star formation. In this talk, I will present results of my research on outflows, jets, and masers using radio interferometric data, and also review recent discoveries in the IR and high energy regime.
