Dynamical double black holes and their host cluster properties
Debatri Chattopadhyay, Jarrod Hurley, Simon Stevenson +1
We investigate the relationship between the global properties of star clusters and their double black hole (DBH) populations. We use the code {\tt NBODY6} to evolve a suite of star…
No evidence for intermediate-mass black holes in the globular clusters Cen and NGC 6624
Holger Baumgardt, Chenyu He, Sarah M. Sweet +8
We compare the results of a large grid of N-body simulations with the surface brightness and velocity dispersion profiles of the globular clusters Cen and NGC 6624. Our models…
Mass Evaporation Rate of Globular Clusters in a Strong Tidal Field
Juan P. Madrid, Nathan W. C. Leigh, Jarrod R. Hurley +1
The mass evaporation rate of globular clusters evolving in a strong Galactic tidal field is derived through the analysis of large, multi-mass -body simulations. For comparison,…
Evolution of star cluster systems in isolated galaxies: first results from direct -body simulations
L. J. Rossi, K. Bekki, J. R. Hurley
The evolution of star clusters is largely affected by the tidal field generated by the host galaxy. It is thus in principle expected that under the assumption of an "universal" ini…
A dynamical gravitational wave source in a dense cluster
Jarrod R. Hurley, Anna C. Sippel, Christopher A. Tout +1
Making use of a new N-body model to describe the evolution of a moderate-size globular cluster we investigate the characteristics of the population of black holes within such a clu…
The Globular Cluster System of NGC 6822
J. Veljanoski, A. M. N. Ferguson, A. D. Mackey +11
We present a comprehensive analysis of the globular cluster (GC) system of the Local Group dwarf irregular galaxy NGC 6822. Our study is based on homogeneous optical and near-IR ph…
