TL;DR
Nuclear star clusters are common stellar systems at galaxy centers, whose formation, growth, and evolution are linked to galaxy development and possibly connected to black holes and globular clusters.
Contribution
This review synthesizes recent research on nuclear star clusters, discussing their formation, growth, and evolutionary relationships with black holes and globular clusters.
Findings
NCs are present in all galaxy types.
They have stellar origins based on structural and spectral properties.
Potential evolutionary links with supermassive black holes and globular clusters.
Abstract
The centers of most galaxies in the local universe are occupied by compact, barely resolved sources. Based on their structural properties, position in the fundamental plane, and integrated spectra, these sources clearly have a stellar origin. They are therefore called "nuclear star clusters" (NCs) or "stellar nuclei". NCs are found in galaxies of all Hubble types, suggesting that their formation is intricately linked to galaxy evolution. Here, I review some recent studies of NCs, describe ideas for their formation and subsequent growth, and touch on their possible evolutionary connection with both supermassive black holes and globular clusters.
