  "abstract": "We present the results of a deep 251 ks XRISM/Resolve observation of the cool core of the galaxy cluster Abell 2199. From the integrated spectrum of the central $3' \\times 3'$ Resolve field of view ($104 \\times 104 \\mathrm{~kpc}^2$), we find that the intracluster medium (ICM) redshift is consistent with that of the brightest cluster galaxy, within the optical-redshift uncertainty. This indicates that they form a kinematically coherent core system, which is offset from the mean cluster redshift by $\\sim200~\\mathrm{km~s^{-1}}$. The observed velocity dispersion of $\\sim100~\\mathrm{km~s^{-1}}$ corresponds to a three-dimensional Mach number of $M_{\\mathrm{3D}}=0.16$ and a non-thermal pressure fraction of $P_{\\mathrm{NT}}/P_{\\mathrm{tot}}=1.4\\pm0.2$%. Abell 2199 is one of the most dynamically quiescent relaxed clusters observed with XRISM, despite the presence of radio jets and a plume-like structure possibly associated with sloshing motions. Order-of-magnitude estimates suggest that turbulent dissipation could offset a non-negligible fraction of the radiative cooling losses, with $Q_{\\mathrm{turb}}/Q_{\\mathrm{cool}}\\approx0.2$ for a large-scale driver such as sloshing and larger values for smaller AGN-feedback scales. Finally, we detect a localized enhancement of the Fe XXV He$α$ $y$ line in the southeast region, which spatially coincides with a Chandra surface brightness discontinuity.",
