A stellar census in globular clusters with MUSE: Binaries in NGC 3201
Benjamin Giesers, Sebastian Kamann, Stefan Dreizler +8
We utilize multi-epoch MUSE spectroscopy to study binaries in the core of NGC 3201. Our sample consists of 3553 stars with 54883 spectra in total comprising 3200 main-sequence star…
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…
Are most Cataclysmic Variables in Globular Clusters dynamically formed?
Diogo Belloni, Mirek Giersz, Liliana E. Rivera Sandoval +2
We have been investigating populations of cataclysmic variables (CVs) in a set of more than 300 globular cluster (GC) models evolved with the MOCCA code. One of the main questions…
Single-single gravitational-wave captures in globular clusters: Eccentric deci-Hertz sources observable by DECIGO and Tian-Qin
Johan Samsing, Daniel J. D'Orazio, Kyle Kremer +2
We study the formation rate of binary black hole mergers formed through gravitational-wave emission between unbound, single black holes in globular clusters. While the formation of…
