A star cluster in a galactic nucleus sinks toward the galactic center because of dynamical friction. As it spirals inward, the cluster loses mass through stellar evolution, relaxation driven evaporation, and tidal stripping, eventually dissolving in the galactic tidal field. We model the in-spiral of dense young star clusters near the center of our Galaxy to study the extent of the region of parameter space in which the cluster can reach the inner parsec of the Galaxy within a few million years… Expand

The Disruption of stellar clusters containing massive black holes near the Galactic Center
We present results from dynamical Monte Carlo simulations of dense star clusters near the Galactic center. These clusters sink toward the center of the Galaxy by dynamical friction. During theirExpand
The Ecology of Star Clusters and Intermediate-Mass Black Holes in the Galactic Bulge
We simulate the inner 100 pc of the Milky Way to study the formation and evolution of the population of star clusters and intermediate-mass black holes (IMBHs). For this study we perform extensiveExpand
Cluster Core Dynamics in the Galactic Center
We present results of N-body simulations aimed at understanding the dynamics of young stars near the Galactic center. Specifically, we model the inspiral of a cluster core containing anExpand
The influence of mass‐loss from a star cluster on its dynamical friction – I. Clusters without internal evolution
Many Local Group dwarf spheroidal galaxies are found in the Galactic halo along great circles in the sky. Some of these stellar systems are thought to be the fragments of larger parent galaxies whichExpand
Massive Young Clusters Near the Galactic Center
In this chapter, I review studies of the three massive young clusters at the Galactic Center—Arches, Quintuplet, and the Young Nuclear Cluster. These clusters reside in an extreme environment and areExpand
Nuclear Star Clusters from Clustered Star Formation
Photometrically distinct nuclear star clusters (NSCs) are common in late-type disk and spheroidal galaxies. The formation of NSCs is inevitable in the context of normal star formation in which aExpand
Constraints on the Stellar Mass Function from Stellar Dynamics at the Galactic Center
We consider the dynamical evolution of a disk of stars orbiting a central black hole. In particular, we focus on the effect of the stellar mass function on the evolution of the disk, using bothExpand
Young stars in the Galactic Centre: a potential intermediate-mass star origin
There has been recent speculation that the cores of intermediate-mass stars stripped of their envelopes by tidal interaction with the supermassive black hole in the Galactic Centre could form aExpand
Massive stars: From Pop III and GRBs to the Milky Way: Massive-star formation in the Galactic center
The Galactic center is a hotbed of star formation activity, containing the most massive star formation site and three of the most massive young star clusters in the Galaxy. Given such a richExpand
Dynamical Friction on Galactic Center Star Clusters with an Intermediate-Mass Black Hole
Numerical simulations of the dynamical friction suffered by a Galactic center star cluster harboring an intermediate-mass black hole (IMBH) have been performed. Gerhard has suggested that dynamicalExpand

The accelerations of stars orbiting the Milky Way's central black hole
TLDR
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*.
