The VISTA near-infrared Y, J, Ks survey of the Magellanic System (VMC) survey is obtaining multi-epoch photometry in the Ks band of the Magellanic System down to a limiting magnitude of Ks ∼ 19.3 for individual epoch data. The observations are spaced... Read More about The VMC Survey – X. Cepheids, RR Lyrae stars and binaries as probes of the Magellanic System's structure★.

SURVEYING THE AGENTS OF GALAXY EVOLUTION IN THE TIDALLY STRIPPED, LOW METALLICITY SMALL MAGELLANIC CLOUD (SAGE-SMC). III. YOUNG STELLAR OBJECTS (2013)
Journal Article

The Spitzer Space Telescope Legacy Program SAGE-SMC allows global studies of resolved stellar populations in the SMC in a different environment than our Galaxy. Using the SAGE-SMC IRAC (3.6–8.0 μm) and MIPS (24 and 70 μm) catalogs and images combined...
