Impact of initial mass function on the chemical evolution of high-redshift galaxies
Boyuan Liu, Michela Mapelli, Volker Bromm +10
Recent observations by the James Webb Space Telescope (JWST) have found evidence for an invariant relation between stellar mass, metallicity, and star formation rate up to $z\sim 8…
Impact of accretion-induced chemically homogeneous evolution on stellar and compact binary populations
Marco Dall'Amico, Michela Mapelli, Giuliano Iorio +5
In binary star systems, mass transfer can spin up the accretor, possibly leading to efficient chemical mixing and chemically quasi-homogeneous evolution (CHE). Here, we explore the…
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…
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-…
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…
Nebular emission from young stellar populations including binary stars
M. Lecroq, S. Charlot, A. Bressan +8
We investigate the nebular emission produced by young stellar populations using the new GALSEVN model based on the combination of the SEVN population-synthesis code including binar…
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…
One to many: comparing single gravitational-wave events to astrophysical populations
Matthew Mould, Davide Gerosa, Marco Dall'Amico +1
Gravitational-wave observations have revealed sources whose unusual properties challenge our understanding of compact-binary formation. Inferring the formation processes that are b…
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…
Compact object mergers: exploring uncertainties from stellar and binary evolution with SEVN
Giuliano Iorio, Michela Mapelli, Guglielmo Costa +9
Population-synthesis codes are an unique tool to explore the parameter space of massive binary star evolution and binary compact object (BCO) formation. Most population-synthesis c…
Study on the detectability of gravitational radiation from single-binary encounters between black holes in nuclear star cluster: the case of hyperbolic flybys
Elena Codazzo, Matteo Di Giovanni, Jan Harms +2
With the release of the third Gravitational-Wave Transient Catalogue (GWTC-3), 90 observations of compact-binary mergers by Virgo and LIGO detectors are confirmed. Some of these me…
The dynamical origin of GW190521 in young massive star clusters
Marco Dall'Amico
GW190521 is the most massive binary black hole (BBH) merger observed to date. Due to its peculiar properties, the origin of this system is still a matter of debate: several hints m…
Intermediate mass black holes from stellar mergers in young star clusters
Ugo N. Di Carlo, Michela Mapelli, Mario Pasquato +8
Intermediate mass black holes (IMBHs) in the mass range bridge the gap between stellar black holes (BHs) and supermassive BHs. Here, we investigate…
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…
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…
