The Local Group as an Astrophysical Laboratory for Massive Star Feedback
M. S. Oey
The feedback effects of massive stars on their galactic and intergalactic environments can dominate evolutionary processes in galaxies and affect cosmic structure in the Universe.…
HI as a Probe of Structure in the Interstellar Medium of External Galaxies
M. S. Oey
This review presents a perspective on recent advances in understanding neutral ISM structure in external galaxies. HI is a fundamental probe of galactic baryonic material, and its…
Mechanical Feedback: From stellar wind bubbles to starbursts
M. S. Oey, C. J. Clarke, P. Massey
The current understanding of mechanical feedback is reviewed by evaluating the standard, adiabatic model for shell formation and evolution. This model is relevant to phenomena rang…
Calibrating nebular diagnostics of T_* and abundance
M. S. Oey, J. C. Shields, M. A. Dopita +1
We obtained nebular spectroscopy of LMC HII regions having classified stellar populations, thereby strongly constraining the ionization input parameters. Using photoionization mode…
Superbubbles in the Magellanic Clouds
M. S. Oey
Superbubbles that result from the stellar winds and supernovae of OB associations probably play a fundamental role in the structure and energetics of the ISM in star-forming galaxi…
The Size Distribution of Superbubbles in the Interstellar Medium
M. S. Oey, C. J. Clarke
We use the standard, adiabatic shell evolution to predict the size distribution N(R) for populations of SN-driven superbubbles in a uniform ISM. We derive N(R) for simple cases of…
