The nuclear star cluster at the Galactic Centre

AuthorsSchödel, Rainer

CitationColloquium Max Planck Institute for Radio Astronomy (2019)
AbstractSagittarius A\*, the Milky Way's central four million solar mass black hole, is surrounded by a star cluster of roughly 25 million solar masses. This cluster appears to be similar to the nuclear clusters that are observed in the majority of galaxies. In this talk I will review our current knowledge about the nuclear cluster of the Milky Way and present some yet unpublished results. Our analysis of the star formation history excludes a quasi-continuous star formation and shows that the cluster is mostly very old (~10 Gyr) and metal rich (about twice solar), which gives us some clues as to its formation. A few percent of its mass formed in the last ~300 Myr. There appears to exist the predicted stellar density cusp around Sagittarius A*, which is of great relevance for the potential future detection of extreme mass ratio inspiral events from similar systems by space-based gravitational wave observatories.
