Why areNuclear Star Clusters interesting? 1) Many -- if not all ­ nuclear star clusters appear to be young, or at least have a young population of stars. ... 3) If nuclear clusters indeed form in the galaxy center, their impact on the dynamics of stars and gas in the central region of the host galaxy needs to be understood, because it can potentially influence the galaxy morphology. For example, it has been suggested that nuclear clusters can destroy stellar bars and thus form galaxy bulges. ...
