The Morpho-kinematic Architecture of Super Star Clusters in the Center of NGC 253

Abstract The center of the nearby galaxy NGC 253 hosts a population more than dozen super star clusters (SSCs) that are still in process forming. majority formation burst is concentrated these SSCs, and starburst powering multiphase outflow from galaxy. In this work, we measure 350 GHz dust continuum emission toward at 47 mas (0.8 pc) resolution using data Atacama Large Millimeter/submillimeter Array. We report detection (dust) for first time, associated with prominent South-West streamer. feature, has width ?8 pc, located outer edge CO emission, corresponds to molecular gas mass ?(8–17)×10 6 M ? . nucleus, resolved radial profiles, sizes, masses SSCs. Compared previous work somewhat lower spatial resolution, SSCs here break apart into smaller substructures radii 0.4–0.7 pc. projection, dust, dense appear be arranged as thin, almost linear, structure roughly 155 pc length. morphology kinematics can well explained following x 2 orbits barred potential. constrain morpho-kinematic arrangement themselves, finding an elliptical, angular-momentum-conserving ring good description both
