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…

A binary black hole merger rate comparison within the same metallicity-star formation rate framework
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
Recent studies have suggested that binary population synthesis models, when coupled with observationally based, metallicity-dependent SFRD, overpredict the observed local BBH merge…

Can current models predict the local black hole merger rate?
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
After four observational runs, the Ligo-Virgo-Kagra collaboration estimated a local binary black hole (BBH) merger rate density of $R_{0,\textrm{LVK}}\simeq 14-26\,\textrm{Gpc}^{-3…
