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…
Breaking binary formation mechanism degeneracies with gravitational wave clustering
Nicola Bellomo, Michele Bosi, Sarah Libanore +4
Thanks to the almost 400 gravitational wave events detected, we are currently able to grasp the fundamental features of black hole mass, spin, and distance distributions. However,…
Pebbles to Gems: Intermediate-mass black holes in the first star clusters
Benedetta Mestichelli, Manuel Arca Sedda, Marta Volonteri +9
The rapid assembly of supermassive black holes (SMBHs) observed at requires efficient seeding mechanisms in the early Universe. Population III (Pop. III) star clusters…
Intermediate-mass black hole seeding in galactic nuclei from star cluster migration
Stefano Torniamenti, Nils Hoyer, Nadine Neumayer +2
Nuclear star clusters are one of the most favorable sites to host hierarchical black hole (BH) mergers, potentially bridging the gap from stellar-mass to massive BHs. However, thei…
Investigating the formation channel of GW231123: Population III stars or hierarchical mergers?
Federico Angeloni, Konstantinos Kritos, Raffaella Schneider +5
The gravitational wave event GW231123, with component black hole masses lying within or above the pair-instability mass gap, poses a significant challenge to current stellar evolut…
