Stellar-mass black holes in young massive and open stellar clusters and their role in gravitational-wave generation II
@inproceedings{Banerjee2017StellarmassBH, title={Stellar-mass black holes in young massive and open stellar clusters and their role in gravitational-wave generation II}, author={Sambaran Banerjee}, year={2017} }
The study of stellar-remnant black holes (BH) in dense stellar clusters is now in the spotlight, especially due to their intrinsic ability to form binary black holes (BBH) through dynamical encounters, that potentially coalesce via gravitational-wave (GW) radiation. In this work, which is a continuation from a recent study (Paper I), additional models of compact stellar clusters with initial masses . 105M and also those with small fractions of primordial binaries (. 10%) are evolved for long…
