Progressive star formation in the young SMC cluster NGC 602
Lynn Redding Carlson, E. Sabbi, M. Sirianni +9
NGC 602 is a young stellar cluster located in a peripheral region of the Small Magellanic Cloud known as the wing. Far from the main body of the galaxy and abutting the Magellanic…
The nature of the metal-rich thick disk
T. Bensby, A. R. Zenn, M. S. Oey +1
We have traced the Galactic thick disk to its, to date, highest metallicities. Based on high-resolution spectroscopic observations of 187 F and G dwarf stars that kinematically can…
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…
