Optically thick winds of very massive stars suppress intermediate-mass black hole formation
Stefano Torniamenti, Michela Mapelli, Lumen Boco +3
Intermediate-mass black holes (IMBHs) are the link between stellar-mass and supermassive black holes. Gravitational waves have started unveiling a population of IMBHs in the $\sim…
Modeling gravitational wave sources in the MillenniumTNG simulations
Federico Marinacci, Marco Baldi, Giuliano Iorio +5
(Edited) We introduce a flexible framework for building gravitational wave (GW) event catalogs in hydrodynamic simulations of galaxy formation. Our framework couples the state-of-t…
Reconstructing the origin of black hole mergers using sparse astrophysical models
V. Gayathri, Giuliano Iorio, Hiromichi Tagawa +8
The astrophysical origin of binary black hole mergers discovered by LIGO and Virgo remains uncertain. Efforts to reconstruct the processes that lead to mergers typically rely on ei…
Black Hole - Neutron Star and Binary Neutron Star Mergers from Population III and II stars
Benedetta Mestichelli, Michela Mapelli, Filippo Santoliquido +9
Population III (Pop.III) stars are expected to be massive and to undergo minimal mass loss due to their lack of metals, making them ideal progenitors of black holes and neutron…
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…
FROST-CLUSTERS -- II. Massive stars, binaries and triples boost supermassive black hole seed formation in assembling star clusters
Antti Rantala, Natalia Lahén, Thorsten Naab +2
Observations and high-resolution hydrodynamical simulations indicate that massive star clusters form through a complex hierarchical assembly. We use simulations including post-Newt…
Impact of stellar winds on the pair-instability supernova rate
Filippo Simonato, Stefano Torniamenti, Michela Mapelli +4
Very massive stars (VMSs, 100 M) play a crucial role in several astrophysical processes. At low metallicity, they might collapse directly into black ho…
A new prescription for the spectral properties of population III stellar populations
Marie Lecroq, Stéphane Charlot, Alessandro Bressan +7
We investigated various emission properties of extremely low metallicity stellar populations in the Epoch of Reionization (EoR), using the new GALSEVN model, which has shown promis…
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…
