We present observations of the nuclear star cluster in the nearby edge-on spiral galaxy NGC 4244 using the Gemini Near-Infrared Integral Field Spectrograph ( NIFS ) with laser guide star adaptive optics . From a previous study of edge-on galaxies , this nuclear star cluster was found to be one of a sample of clusters that appear flattened along the plane of their host galaxies disks . Such clusters show evidence for multiple morphological components , with younger/bluer disk components and older/redder spheroidal components . Our new observations of NGC 4244 show clear rotation of 30 km s ^ { -1 } within the central 10 pc ( 0.5 \arcsec ) of the cluster . The central velocity dispersion is found to be 28 \pm 2 km s ^ { -1 } . The multiple stellar populations inferred from the optical colors and spectra are seen as variations in the CO line strength in the NIFS spectra . The rotation is clearly detected even in the older , more spheroidal stellar component . We discuss evidence for similar structures and kinematics in the nuclear star clusters of other galaxies including M33 and the Milky Way . Our observations support two possible formation mechanisms : ( 1 ) episodic accretion of gas from the disk directly onto the nuclear star cluster , or ( 2 ) episodic accretion of young star clusters formed in the central part of the galaxy due to dynamical friction .
