Compact Star Clusters in Nearby Dwarf Irregular Galaxies
Olivia H. Billett, Deidre A. Hunter, Bruce G. Elmegreen
Nearby dwarf irregular galaxies were searched for compact star clusters using data from the HST archives. Three of the galaxies were found to host both populous clusters (M_V<-9.5…
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…
The HI Environment of Three Superbubbles in the Large Magellanic Cloud
M. S. Oey, B. Groves, L. Staveley-Smith +1
The ambient interstellar environment of wind- and supernova-driven superbubbles strongly affects their evolution, but its properties are rarely well-determined. We have therefore o…
The Magellanic Clouds Photometric Survey: The Small Magellanic Cloud Stellar Catalog and Extinction Map
Dennis Zaritsky, Jason Harris, Ian B. Thompson +2
We present our catalog of U, B, V, and I stellar photometry of the central 18 sq. degree area of the Small Magellanic Cloud. We combine our data with the 2MASS and DENIS catalogs t…
Astrometry with Hubble Space Telescope: A Parallax of the Fundamental Distance Calibrator RR Lyrae
G. Fritz Benedict, B. E. McArthur, L. W. Fredrick +16
We present an absolute parallax and relative proper motion for the fundamental distance scale calibrator, RR Lyr. We obtain these with astrometric data from FGS 3, a white-light in…
Orbits of Four Very Massive Binaries in the R136 Cluster
Philip Massey, Laura R. Penny, Julia Vukovich
We present radial velocity and photometry for four early-type, massive double-lined spectroscopic binaries in the R136 cluster. Three of these systems are eclipsing, allowing orbit…
