Título: "Investigating the Early Phases of Massive Star Formation Using 6.7 GHz Methanol Masers"

Abstract:

Understanding how massive stars form remains one of the central challenges in astrophysics because their earliest stages are deeply embedded within dense clouds of gas and dust. Class II 6.7 GHz methanol masers are among the best tracers of these young massive stellar objects, making them powerful probes of the earliest phases of high-mass star formation. In this talk, I will present my work based on the Global View of Star Formation in the Milky Way (GLOSTAR) survey, a sensitive, high-resolution radio survey of the Galactic plane that has significantly expanded the known population of 6.7 GHz methanol masers. Using ATLASGAL and Herschel/Hi-GAL data, we derive the physical properties of the dust clumps associated with these masers through spectral energy distribution fitting. We also investigate whether maser luminosity correlates with the physical properties of the host clumps, providing insight into whether maser luminosity can serve as a tracer of specific evolutionary phases in high-mass star formation. Finally, I will briefly discuss the ongoing work from the Very Large Orion Survey (VOLS), aimed at investigating radio emission from young stellar objects in the Orion molecular cloud. Together, these studies provide new insights into the environments and evolution of young stars across different mass regimes.
