Multimass modelling of Milky Way globular clusters -- II. present-day black hole populations
Nolan Dickson, Peter J. Smith, Vincent Hénault-Brunet +2
Populations of stellar-mass black holes (BHs) in globular clusters (GCs) influence their dynamical evolution and have important implications on one of the main formation channels f…
A black hole detected in the young massive LMC cluster NGC 1850
S. Saracino, S. Kamann, M. G. Guarcello +8
We report the detection of a black hole (NGC 1850 BH1) in the 100 Myr-old massive cluster NGC~1850 in the Large Magellanic Cloud. It is in a binary system with a main-sequenc…
On the black hole content and initial mass function of 47 Tuc
Vincent Hénault-Brunet, Mark Gieles, Jay Strader +3
The globular cluster (GC) 47 Tuc has recently been proposed to host an intermediate-mass black hole (IMBH) or a population of stellar-mass black holes (BHs). To shed light on its d…
Mass modelling globular clusters in the Gaia era: a method comparison using mock data from an -body simulation of M4
Vincent Hénault-Brunet, Mark Gieles, Antonio Sollima +5
As we enter a golden age for studies of internal kinematics and dynamics of Galactic globular clusters (GCs), it is timely to assess the performance of modelling techniques in reco…
Linking the rotation of a cluster to the spins of its stars: The kinematics of NGC6791 and NGC6819 in 3D
Sebastian Kamann, Nate Bastian, Mark Gieles +2
The physics governing the formation of star clusters is still not entirely understood. One open question concerns the amount of angular momentum that newly formed clusters possess…
Radial anisotropy in omega Cen limiting the room for an intermediate-mass black hole
Alice Zocchi, Mark Gieles, Vincent Hénault-Brunet
Finding an intermediate-mass black hole (IMBH) in a globular cluster (or proving its absence) would provide valuable insights into our understanding of galaxy formation and evoluti…
Testing lowered isothermal models with direct N-body simulations of globular clusters - II: Multimass models
Miklos Peuten, Alice Zocchi, Mark Gieles +1
Lowered isothermal models, such as the multimass Michie-King models, have been successful in describing observational data of globular clusters. In this study we assess whether suc…
Testing lowered isothermal models with direct N-body simulations of globular clusters
Alice Zocchi, Mark Gieles, Vincent Hénault-Brunet +1
Several self-consistent models have been proposed, aiming at describing the phase space distribution of stars in globular clusters. This study explores the ability of the recently…
No evidence for younger stellar generations within the intermediate age massive clusters NGC 1783, NGC 1696 and NGC 411
I. Cabrera-Ziri, F. Niederhofer, N. Bastian +11
Recently, Li et al. (2016) claimed to have found evidence for multiple generations of stars in the intermediate age clusters NGC 1783, NGC 1696 and NGC 411 in the Large and Small M…
Multiple populations in globular clusters: the distinct kinematic imprints of different formation scenarios
Vincent Hénault-Brunet, Mark Gieles, Oscar Agertz +1
Several scenarios have been proposed to explain the presence of multiple stellar populations in globular clusters. Many of them invoke multiple generations of stars to explain the…
