# The Properties of Nuclear Star Clusters and their Host Galaxies

## TL;DR

This paper reviews the prevalence, properties, and formation mechanisms of nuclear star clusters across various galaxy types and masses, highlighting their unique stellar dynamics and the different processes driving their formation.

## Contribution

It provides a comprehensive overview of the properties and formation theories of nuclear star clusters, emphasizing the variation with galaxy mass and type.

## Key findings

- Nuclear star clusters are common in most galaxy centers.
- Different formation mechanisms dominate in low- and high-mass galaxies.
- NSCs exhibit unique stellar dynamics due to their density.

## Abstract

Nuclear star clusters are found at the centers of most galaxies. They are the densest stellar systems in the Universe, and thus have unique and interesting stellar dynamics. We review how common nuclear star clusters are in galaxies of different masses and types, and then discuss the typical properties of NSCs. We close by discussing the formation of NSCs, and how a picture is emerging of different formation mechanisms being dominant in lower and higher mass galaxies.
