Black hole spin-mass correlation and accretion disks at birth stage of dense star clusters
Zacharias Roupas
We review the accretion-driven channel of stellar black-hole growth and spin-up in gaseous star clusters, developed within the framework of our MSCA project "protoBH". Our detailed…
Evidence for an accretion-driven subpopulation of black holes in GWTC-5.0
Zacharias Roupas
We report Bayesian evidence for a subpopulation of black holes, grown via accretion during the gaseous birth-stage of star clusters, in the cumulative GWTC-5.0 released by the LIGO…
Black hole spin-mass correlation and vector resonant relaxation in gaseous star clusters: the origin of GW231123?
Zacharias Roupas
During the formation of a star cluster a spin-mass correlation of stellar black holes is generated as they grow via accretion of the residual gas. Moreover, the black hole spin ten…
Accretion-disk formation around orbiting stellar black holes in gaseous star clusters
Zacharias Roupas
We consider low-mass black holes (BHs) moving in regular orbits in the cores of non-rotating gaseous star clusters, representative of proto-stellar clusters or the centers of proto…
Spin-up and spin distribution of stellar black holes grown by gas accretion in proto-stellar clusters
Zacharias Roupas
Proto-stellar clusters, likely progenitors of globular clusters, are compact with typical mass and size , as revealed recently by JWST…
Massive Black Hole formation in proto-stellar clusters via early gas accretion
Zacharias Roupas
We review our semi-analytic model of stellar black hole (BH) mass growth by gas accretion in gas-rich stellar clusters during their birthstage within the first …
