We present parsec-scale kinematics of eleven nearby galactic nuclei, derivedfrom adaptive-optics assisted integral-field spectroscopy at (near-infrared) COband-head wavelengths. We focus our analysis on the balance between orderedrotation and random motions, which can provide insights into the dominantformation mechanism of nuclear star clusters (NSCs). We divide our targetsample into late- and early-type galaxies, and discuss the nuclear kinematicsof the two sub-samples, aiming at probing any link between NSC formation andhost galaxy evolution. The results suggest that the dominant formationmechanism of NSCs is indeed affected by the different evolutionary paths oftheir hosts across the Hubble sequence. More specifically, nuclear regions inlate-type galaxies are on average more rotation dominated, and the formation ofnuclear stellar structures is potentially linked to the presence of gasfunnelled to the center. Early-type galaxies, in contrast, tend to displayslower-rotating NSCs with lower ellipticity. However, some exceptions suggestthat in specific cases, early-type hosts can form NSCs in a way similar tospirals.

Resolved nuclear kinematics link the formation and growth of nuclear star clusters with the evolution of their early and late-type hosts
