The ESO-VLT MIKiS Survey Reloaded: Velocity Dispersion Profile and Rotation Curve of NGC 1904*

We present an investigation of the internal kinematic properties M79 (NGC 1904). Our study is based on radial velocity measurements obtained from ESO-VLT Multi-Instrument Kinematic Survey (MIKiS) Galactic globular clusters for more than 1700 individual stars distributed between $\sim 0.3^{\prime\prime}$ and $770^{\prime\prime}$ ($\sim14$ three-dimensional half-mass radii), center. analysis reveals presence ordered line-of-sight rotation with a axis almost aligned along East-West direction peak $1.5$ km s$^{-1}$ at 70^{\prime\prime}$ axis. The dispersion profile well described by same King model that best fits projected density distribution, constant central plateau $\sigma_0\sim 6$ s$^{-1}$. To investigate cluster in plane sky, we have analyzed proper motions provided Gaia EDR3, finding signature maximum amplitude 2.0$ 80^{\prime\prime}$ Analyzing sub-sample 130 stars, confirm systemic find inclination angle $37${\deg} respect to line-of-sight. As final result, comparison observed curves results representative N-body simulation rotating star shows present-day NGC 1904 are consistent those dynamically old system has lost significant fraction its initial angular momentum.
