In order to study the gaseous and stellar kinematics and the star formation properties of the clusters, we perform seeing-limited $H+K$-band near-infrared integral-field spectroscopy with SINFONI of the inner $\\sim 600\\,\\mathrm{pc}$. From the $M_\\mathrm{BH}-\\sigma_*$ relation, we find a black hole mass of a few $10^7\\,M_\\odot$. We estimate the age of the young stellar clusters in the circumnuclear ring to be $\\lesssim 10\\,\\mathrm{Myr}$.
