Title: Revealing the Properties of Embedded Clusters Beyond the Milky Way

Abstract: We propose to use GeMs/GSAOI on Gemini South to obtain high- resolution near-infrared images of 6 embedded clusters in the LMC. We have obtained H+K band IFU spectra of two of these clusters using SINFONI. High-resolution images are critical for the analysis and interpretation of our SINFONI data. The GeMs/GSAOI images will allow us to determine which sources are dominating the spectrum in each spaxel so we can see what is really inside each of the SINFONI spectra. The combination of SINFONI and GeMs/GSAOI data opens up a new parameter space, in that we will obtain spectroscopy and high-resolution imaging of embedded clusters for the first time, and characterize their properties with a level of detail that is comparable to Milky Way embedded clusters. This investigation will provide crucial data to tackle fundamental issues, including understanding the embedded stellar cluster mass function in the LMC, the rate and efficiency of star formation in LMC GMCs and the sensitivity of these properties to global environmental factors such as metallicity.
