Dynamical formation of dormant black holes: Predictions for Gaia DR4
Daniel Marín Pina, Michela Mapelli, Giuliano Iorio +1
Dormant black holes (dormant BHs, i.e., X-ray quiet binaries comprising a BH and a companion star) are probes of the effect of cluster dynamics and binary stellar evolution on comp…
A "universal" supernova efficiency to drive the HI turbulence in nearby star-forming galaxies
Lauri Sassali, Cecilia Bacchini, Aku Venhola +2
The origin of cold gas turbulence in galaxies has long been debated. Supernovae (SNe), the dominant form of stellar feedback, were thought insufficient to sustain it against dissip…
Linking high-mass X-ray binaries to binary compact object mergers in Milky Way-like galaxies
Felipe Vivanco Cádiz, M. Celeste Artale, Nicola Masetti +5
High-mass X-ray binaries (HMXBs) constitute a potential intermediate phase connecting massive stellar binaries to the formation of coalescing binary compact objects (BCOs). Yet, th…
The impact of stellar binaries and star cluster dynamics on pair-instability supernovae
Francesco Gabrielli, Cristiano Ugolini, Lavinia Paiella +12
Pair-instability supernovae (PISNe) are among the most luminous transients in the Universe. However, they have never been confidently observed. Solving this puzzle would have key i…
The role of mass transfer efficiency in stability criteria: Implementation in SEVN and a test on blue stragglers and binary compact objects
M. Echeveste, G. J. Escobar, G. Iorio +12
Context: The stability of mass transfer through Roche-lobe overflow plays a key role in shaping the outcome of binary interactions. However, the criterion for mass transfer stabili…
The impact of envelope binding energies on the merger rate density of binary compact objects
Cecilia Sgalletta, Guglielmo Costa, Giuliano Iorio +8
The common envelope (CE) phase plays a key role in the formation of binary compact object systems. Its final outcome strongly depends on the envelope binding energy, but this quant…
Population synthesis of Be X-ray binaries in the Small Magellanic Cloud: Angular momentum recycling and stable mass transfer
Víctor López Oller, Boyuan Liu, Michela Mapelli +5
Be X-ray binaries (BeXRBs) are key laboratories to constrain binary interaction processes such as mass transfer, angular-momentum transport, and natal kicks. The Small Magellanic C…
-body modelling of the ED-2 stream progenitor shows Gaia BH3's formation involved dynamical interactions
Daniel Marín Pina, Mark Gieles, Sara Rastello +3
Context. The Gaia collaboration announced the discovery of a binary of a massive black hole (33 M) with a low-mass giant star (Gaia BH3) in the ED-2 stellar stream. The pro…
The role of accretion efficiency, natal kicks, and angular momentum transport in the formation of the Gaia black holes
Michela Mapelli, Cecilia Sgalletta, Johanna Müller-Horn +5
Gaia has the potential to deliver several tens of new dormant black holes (BHs) with low-mass stellar companions (hereafter, Gaia BHs) in the upcoming fourth data release. Three Ga…
Advanced Virgo Plus for O5 -- Design Report Overview
F. Acernese, A. Agapito, D. Agarwal +578
This document presents an overview of the design, implementation, and expected performance of the Advanced Virgo Plus (AdV+) upgrades in view of the O5 observing run. Following the…
Hide and Seek with Gaia. Detectability of Predicted Thin-Disc Metal-Rich RR Lyrae Binaries in Gaia DR3 and DR4
Giuliano Iorio, Pranav Nagarajan, Alexey Bobrick +8
RR Lyrae stars (RRLs) are classical tracers of old stellar populations, yet growing evidence suggests the presence of a metal-rich ([Fe/H]>-0.5), intermediate-age (2-7 Gyr) sub-pop…
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…

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 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…
