The more accurately the metal-dependent star formation rate is modeled, the larger the predicted excess of binary black hole mergers
Cecilia Sgalletta, Michela Mapelli, Lumen Boco +5
As the number of gravitational-wave detections grows, the merger rate of binary black holes (BBHs) can help us to constrain their formation, the properties of their progenitors, an…
Wolf-Rayet -- compact object binaries as progenitors of binary compact objects
Erika Korb, Michela Mapelli, Giuliano Iorio +2
Binaries with a Wolf-Rayet star and a compact object (WR-COs), either a black hole (BH) or a neutron star (NS), have been proposed as possible progenitors for the binary compact ob…
A machine learning framework to generate star cluster realisations
George P. Prodan, Mario Pasquato, Giuliano Iorio +4
Context. Computational astronomy has reached the stage where running a gravitational N-body simulation of a stellar system, such as a Milky Way star cluster, is computationally fea…
Tidal mass loss in the Fornax dwarf spheroidal galaxy through N-body simulations with Gaia DR3-based orbits
Pierfrancesco Di Cintio, Giuliano Iorio, Francesco Calura +2
The Fornax dwarf spheroidal galaxy (dSph) represents a challenge for some globular cluster (GC) formation models, because an exceptionally high fraction of its stellar mass is lock…
Binary black hole mergers from Population III star clusters
Benedetta Mestichelli, Michela Mapelli, Stefano Torniamenti +5
Binary black holes (BBHs) born from the evolution of Population III (Pop. III) stars are one of the main high-redshift targets for next-generation ground-based gravitational-wave (…
The boring history of Gaia BH3 from isolated binary evolution
Giuliano Iorio, Stefano Torniamenti, Michela Mapelli +15
Gaia BH3 is the first observed dormant black hole (BH) with a mass of M and represents the first confirmation that such massive BHs are associated with metal-…
Classifying binary black holes from Population III stars with the Einstein Telescope: A machine-learning approach
Filippo Santoliquido, Ulyana Dupletsa, Jacopo Tissino +7
Third-generation (3G) gravitational-wave detectors such as the Einstein Telescope (ET) will observe binary black hole (BBH) mergers at redshifts up to . However, an uneq…
