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…
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…
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…
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-…
