Scientific paper

In this poster we present infrared H and K AO data taken with ALTAIR/NIRI on Gemini North of the globular cluster Messier 71. This data represents approximately 22ks of observations in H and 17ks in K, in a field 22x22 arcsec centered on the core of the cluster. These data were secured under superb conditions and will provide an excellent opportunity to pursue our scientific goals. These goals include the observation of the end of hydrogen-burning main sequence in a moderately metal-rich globular cluster and, by fitting the brightness profile and looking for deviations from a King model, we will search for evidence for a central black hole in this cluster.
