The nuclear star cluster of the Milky Way: proper motions and mass

  title={The nuclear star cluster of the Milky Way: proper motions and mass},
  author={Rainer Schoedel and David Merritt and Andreas Eckart},
  journal={Astronomy and Astrophysics},
Context. Nuclear star clusters (NSCs) are located at the photometric and dynamical centers of the majority of galaxies. They are among the densest star clusters in the Universe. The NSC in the Milky Way is the only object of this class that can be resolved into individual stars. The massive black hole Sagittarius A* is located at the dynamical center of the Milky Way NSC. Aims. In this work we examine the proper motions of stars out to distances of 1.0 pc from Sgr A*. The aim is to examine the… Expand
Structure of the nuclear stellar cluster of the Milky Way galaxy
Abstract Nuclear star clusters are unambiguously detected in about 50–70% of spiral and spheroidal galaxies. They have typical half-light radii of 2–5 pc, dynamical mass ranging from 106 – 107 M⊙,Expand
Large scale kinematics and dynamical modelling of the Milky Way nuclear star cluster
Context. Within the central 10 pc of our Galaxy lies a dense cluster of stars. This nuclear star cluster forms a distinct component of the Galaxy, and similar nuclear star clusters are found in mostExpand
The nuclear cluster of the Milky Way: Our primary testbed for the interaction of a dense star cluster with a massive black hole
This article intends to provide a concise overview, from an observational point-of-view, of the current state of our knowledge of the most relevant properties of the Milky Way's nuclear star clusterExpand
The old Nuclear Star Cluster in the Milky Way
We derive new constraints on the mass, rotation, orbit structure and statistical parallax of the Galactic old nuclear star cluster (NSC) and the mass of the supermassive black hole. We combine starExpand
Dissipationless Formation and Evolution of the Milky Way Nuclear Star Cluster
In one widely discussed model for the formation of nuclear star clusters (NSCs), massive globular clusters spiral into the center of a galaxy and merge to form the nucleus. It is now known that atExpand
The nuclear cluster of the Milky Way: total mass and luminosity
Like many other late-type galaxies, the Milky Way contains a nuclear star cluster. In this work we obtain the basic properties of its dominant old stellar population. Firstly, we derive itsExpand
The distribution of stars around the Milky Way's central black hole. I. Deep star counts
Context. The existence of dynamically relaxed stellar density cusps in dense clusters around massive black holes is a long-standing prediction of stellar dynamics, but it has so far escapedExpand
Dust within the nuclear star cluster in the Milky Way
The mean absolute extinction towards the central parsec of the Milky Way is A_K~3 mag, including both foreground and Galactic center dust. Here we present a measurement of dust extinction within theExpand
We present spatially resolved imaging and integral field spectroscopy data for 450 cool giant stars within 1 pc from Sgr A*. We use the prominent CO bandheads to derive effective temperatures ofExpand
The nuclear cluster of the Milky Way: total mass and luminosity
Abstract Here we present the fundamental properties of the nuclear cluster of the Milky Way. First, we derive its structural properties by constructing a density map of the central 1000″ usingExpand


The structure of the nuclear stellar cluster of the Milky Way
Aims. The centre of the Milky Way is the nearest nucleus of a galaxy and offers a unique possibility to study the structure and dynamics of a dense stellar cluster around a super-massive black hole.Expand
The accelerations of stars orbiting the Milky Way's central black hole
Measurements of the accelerations of three stars from the central radio source Sagittarius A* increase the inferred minimum mass density in the central region of the Galaxy by an order of magnitude relative to previous results, and localize the dark mass to within 0.05 ± 0.04 arcsec of the nominal position of Sgr A*.
