dc.description.abstract | Galactic nuclei host central massive objects either in the form of supermassive black holes or in the form of nuclear stellar clusters. Recent investigations have shown that both components co-exist in at least a few galaxies. In this paper, we explore the possibility of a connection between nuclear star clusters and black holes that establishes at the moment of their formation. We here model the evolution of high-redshift discs, hosted in dark matter haloes with virial temperatures > 10 4 K, whose gas has been polluted with metals just above the critical metallicity for fragmentation. A nuclear cluster forms as a result of a central starburst from gas inflowing from the unstable disc. The nuclear stellar cluster provides a suitable environment for the formation of a black hole seed, ensuing from runaway collisions among the most massive stars. Typical masses for the nuclear stellar clusters at the time of black hole formation ( z ∼ 10 ) are in the range 10 4 –10 6 M ⊙ and have half-mass radii ≲ 0.5 pc. The black holes forming in these dense, high-redshift clusters can have masses in the range ∼ 300–2000 M ⊙ . | en_US |
