SUMMARY:Journey: Jets & Outflows Revealing the Nature and Evolution of
  Massive YSO's"\, Astronomy Colloquium\, Esteban Araya\, Western Illin
 ois
DESCRIPTION:High-mass stars are responsible for some of the most spect
 acular astronomical objects such as supernova remnants and stellar mas
 s black holes. High-mass stars form in giant molecular clouds\, genera
 te copious amounts of ionizing photons responsible for the development
  of HII regions\, and drive ionized jets and massive molecular outflow
 s that contribute to the dissipation of their natal clouds. Highlights
  of a multi-scale effort by our group to investigate jets and outflows
  in high-mass star forming regions will be presented. A central compon
 ent of our work has been student involvement in the search and charact
 erization of atomic and molecular tracers of jets\, outflows and the e
 xpansion of ionized gas at microwave frequencies. In particular\, we a
 re studying molecular masers as tracers of dynamic phenomena in high-m
 ass star forming regions\, including long-term variability and periodi
 c flares\, which could be indicative of episodic accretion events in y
 oung binary systems.
