Title: A deep look into nuclear star clusters

Abstract: We propose to observe a sample of 3 nuclear star clusters in low-mass early-type galaxies in the Virgo cluster. Nuclear star clusters can form from accretion of globular clusters at galaxy centers or from in situ star formation. Their evolution is regulated by the energy input from the host galaxy and possibly a supermassive black hole. With this proposal, we try to assemble a unique dataset of kinematic (Gemini/NIFS), stellar population (Gemini/GMOS-S) and morphological (archival HST/ACS) data. The dynamical state, stellar population content and morphology of these clusters will be compared to theoretical calculations to determine the importance of different formation scenarios and possible presence of supermassive black holes.
