Abstract:

We present preliminary results from a high angular resolution study of the inner 5"*5" of the central Galactic stellar cluster. This program was carried out at the W. M. Keck telescope using the facility near-infrared camera with a K[2.2 micron ]-band filter. A few thousand short exposure frames, combined using a shift-and-add algorithm, contribute to the final image which has the diffraction-limited resolution of 0."05. Even prior to deconvolution, sources as faint as ~15th Kmag are detected at the 5 sigma level and new isolated point sources are identified.
