GW190521 formation via three-body encounters in young massive star clusters
Marco Dall'Amico, Michela Mapelli, Ugo N. Di Carlo +5
GW190521 is the most massive binary black hole (BBH) merger observed to date, and its primary component lies in the pair-instability (PI) mass gap. Here, we investigate the formati…
Populating the upper black hole mass gap through stellar collisions in young star clusters
Kyle Kremer, Mario Spera, Devin Becker +6
Theoretical modeling of massive stars predicts a gap in the black hole (BH) mass function above for BHs formed through single star evolution, arising from (…
Gravitational-wave detection rates for compact binaries formed in isolation: LIGO/Virgo O3 and beyond
Vishal Baibhav, Emanuele Berti, Davide Gerosa +4
Using simulations performed with the population synthesis code MOBSE, we compute the merger rate densities and detection rates of compact binary mergers formed in isolation for sec…
Constraining the fraction of binary black holes formed in isolation and young star clusters with gravitational-wave data
Yann Bouffanais, Michela Mapelli, Davide Gerosa +4
Ten binary black-hole mergers have already been detected during the first two observing runs of advanced LIGO and Virgo, and many more are expected to be observed in the near futur…
