Using Binaries in Globular Clusters to Catch Sight of Intermediate-Mass Black Holes

Francisco I. Aros, Anna C. Sippel, Alessandra Mastrobuono-Battisti +3

The dynamical evolution of globular clusters (GCs) is tied to their binary population, as binaries segregate to the cluster centre, leading to an increased binary fraction in the c…

Dynamical modelling of globular clusters: challenges for the robust determination of IMBH candidates

Francisco I. Aros, Anna C. Sippel, Alessandra Mastrobuono-Battisti +3

The presence or absence of intermediate-mass black holes (IMBHs) at the centre of Milky Way globular clusters (GCs) is still an open question. This is either due to observational r…

Formation of super-massive black holes in galactic nuclei I: delivering seed intermediate-mass black holes in massive stellar clusters

Abbas Askar, Melvyn B. Davies, Ross P. Church

Supermassive black holes (SMBHs) are found in most galactic nuclei. A significant fraction of these nuclei also contain a nuclear stellar cluster (NSC) surrounding the SMBH. In thi…

MOCCA-SURVEY Database I: Dissolution of tidally filling star clusters harboring black hole subsystem

Mirek Giersz, Abbas Askar, Long Wang +3

We investigate the dissolution process of star clusters embedded in an external tidal field and harboring a subsystem of stellar-mass black hole. For this purpose we analyzed the M…

Stellar-Mass Black Holes in Globular Clusters: Dynamical Consequences and Observational Signatures

Abbas Askar, Mirek Giersz, Manuel Arca Sedda +3

Sizeable number of stellar-mass black holes (BHs) in globular clusters (GCs) can strongly influence the dynamical evolution and observational properties of their host cluster. Usin…

The Ecology of the Galactic Centre: Nuclear Stellar Clusters and Supermassive Black Holes

Melvyn B. Davies, Abbas Askar, Ross P. Church

Supermassive black holes are found in most galactic nuclei. A large fraction of these nuclei also contain a nuclear stellar cluster surrounding the black hole. Here we consider the…
