Shaping binary black hole merger efficiency with gravitational wave observations
Michele Bosi, Lumen Boco, Stefano Torniamenti +5
Gravitational wave (GW) astronomy offers unprecedented insights into binary black hole (BBH) coalescence. However, many of the key quantities involved remain inaccessible to direct…
Optically thick winds of very massive stars suppress intermediate-mass black hole formation
Stefano Torniamenti, Michela Mapelli, Lumen Boco +3
Intermediate-mass black holes (IMBHs) are the link between stellar-mass and supermassive black holes. Gravitational waves have started unveiling a population of IMBHs in the $\sim…
Impact of stellar winds on the pair-instability supernova rate
Filippo Simonato, Stefano Torniamenti, Michela Mapelli +4
Very massive stars (VMSs, 100 M) play a crucial role in several astrophysical processes. At low metallicity, they might collapse directly into black ho…
Hierarchical binary black hole mergers in globular clusters: mass function and evolution with redshift
Stefano Torniamenti, Michela Mapelli, Carole Périgois +4
Hierarchical black hole (BH) mergers are one of the most straightforward mechanisms to produce BHs inside and above the pair-instability mass gap. Here, we investigate the impact o…
Impact of gas hardening on the population properties of hierarchical black hole mergers in AGN disks
M. Paola Vaccaro, Michela Mapelli, Carole Périgois +5
Hierarchical black hole (BH) mergers in active galactic nuclei (AGNs) are unique among formation channels of binary black holes (BBHs) because they are likely associated with elect…
Eccentric black hole mergers via three-body interactions in young, globular, and nuclear star clusters
Marco Dall'Amico, Michela Mapelli, Stefano Torniamenti +1
Eccentric mergers are a signature of the dynamical formation channel of binary black holes (BBHs) in dense stellar environments and hierarchical triple systems. Here, we investigat…
Hierarchical black hole mergers in young, globular and nuclear star clusters: the effect of metallicity, spin and cluster properties
Michela Mapelli, Marco Dall'Amico, Yann Bouffanais +8
We explore hierarchical black hole (BH) mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs), accounting for both original and dynamicall…
Binary black holes in young star clusters: the impact of metallicity
Ugo N. Di Carlo, Michela Mapelli, Nicola Giacobbo +9
Young star clusters are the most common birth-place of massive stars and are dynamically active environments. Here, we study the formation of black holes (BHs) and binary black hol…
