A Rotating Compact Nuclear Stellar Cluster in NGC 4244

Top - Color show the measure radial velocity observed with NIFS. Blue approaches, green/orange recedes. Rotation of ~30 kilometers/second is clearly visible along the major axis. Bottom – Velocity dispersion across the NSC derived from NIFS measurements. The contour shows the K-band infrared light surface brightness from NIFS. Flattening of the NSC is obvious.
