Modeling interstellar bubbles: near and far

Abstract

In this work, I study the twofold investigation of the interaction of massive stars with their surroundings: I have analyzed observations of emission lines in H II regions to determine the physical conditions surrounding the formation of massive stars both in the near and far Universe; and I have studied the hydrodynamical evolution of these regions numerically. I developed and tested a radiative transfer code as implemented in the hydrodynamic code FLASH. I used the code to study the hydrodynamical evolution and resulting X-ray emission of a prototypical UltraCompact H II region.
