Overview

Thesis explores the properties of HII regions and their environments, shedding light on stellar feedback and star formation dynamics.

Key Points

  • The aim is to characterize Galactic HII regions and understand their relationship with high-mass star formation and the interstellar medium.
  • Conducted a blind search for HII regions using RRL and continuum data from the GLOSTAR survey, cataloging 244 regions.
  • Studied molecular gas associated with 61 HII regions through multiple H2CO transitions using the APEX telescope.
  • Analyzed radio sources in the RCW 106 massive star-forming complex using radio and CO observations from MMGPS.
  • Identified spatial correlations between HII regions and dust/methanol masers, highlighting young stellar objects.
  • Measured electron temperatures across Galactocentric distances and derived a temperature gradient.
  • Found that properties of ionized, molecular gas, and dust are strongly correlated, indicating the regulatory influence of high-mass stars.
