Constraining the high redshift formation of black hole seeds in nuclear star clusters with gas inflows
Alessandro Lupi, Monica Colpi, Bernadetta Devecchi +2
In this paper we explore a possible route of black hole seed formation that appeal to a model by Davies, Miller & Bellovary who considered the case of the dynamical collapse of a d…
Halo millisecond pulsars ejected by intermediate mass black holes in globular clusters
Alberto Sesana, Nicola Sartore, Bernadetta Devecchi +1
Intermediate mass black holes (IMBHs) are among the most elusive objects in contemporary astrophysics. Both theoretical and observational evidence of their existence is subject of…
High-redshift formation and evolution of central massive objects II: The census of BH seeds
B. Devecchi, M. Volonteri, E. M. Rossi +2
We present results of simulations aimed at tracing the formation of nuclear star clusters (NCs) and black hole (BH) seeds, in a cosmological context. We focus on two mechanisms for…
On the offset of Short Gamma-ray Bursts
R. Salvaterra, B. Devecchi, M. Colpi +1
Short Gamma-Ray Bursts (SGRBs) are expected to form from the coalescence of compact binaries, either of primordial origin or from dynamical interactions in globular clusters. In th…
High redshift formation and evolution of central massive objects I: model description
B. Devecchi, M. Volonteri, M. Colpi +1
Galactic nuclei host central massive objects either in the form of supermassive black holes or nuclear stellar clusters. Recent investigations have shown that both components co-ex…
Formation of the first nuclear clusters and massive black holes at high redshift
Bernadetta Devecchi, Marta Volonteri
We present a model for the formation of massive black holes ($\sim 1000 \msun$) due to stellar-dynamical processes in the first stellar clusters formed at early cosmic times ($z\si…
