A binary black hole merger rate comparison within the same metallicity-star formation rate framework
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
Recent studies have suggested that binary population synthesis models, when coupled with observationally based, metallicity-dependent SFRD, overpredict the observed local BBH merge…
The Stellar Winds Atlas II: Black Hole Formation at Solar Metallicity
Amedeo Romagnolo, Floor S. Broekgaarden, Alex C. Gormaz-Matamala +7
Stellar winds are a primary source of uncertainty in predicting the masses of black holes (BHs) from massive stars. At solar metallicity, theoretical models lead to widely divergen…
How Common Are Common Envelopes? Quantifying Their Role in Forming Gravitational-Wave Sources
Floor S. Broekgaarden, Ana Lam, Sasha Levina +14
A central goal of gravitational-wave astronomy is to use merging binary black hole (BBH), black hole-neutron star (BHNS), and binary neutron star (BNS) systems as fossils to recons…
Can current models predict the local black hole merger rate?
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
After four observational runs, the Ligo-Virgo-Kagra collaboration estimated a local binary black hole (BBH) merger rate density of $R_{0,\textrm{LVK}}\simeq 14-26\,\textrm{Gpc}^{-3…
Massquerade: Impacts of Mass Ratio Reversals on Binary Black Hole Merger Rates and Mass Distributions
Tyler B. Smith, Floor Broekgaarden, Sasha Levina +4
We investigate the role of mass ratio reversal (MRR), in which the initially less massive star in a binary forms the more massive compact object, in shaping the astrophysical binar…
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…
From cosmological simulations to binary black hole mergers: The impact of using analytical star formation history models on gravitational-wave source populations
Sasha Levina, Floor Broekgaarden, Lieke van Son +4
Observations of binary black hole (BBH) mergers provide a unique window into the lives of massive stars across cosmic time. Connecting redshift-dependent merger properties to massi…
The Stellar Winds Atlas I: Current uncertainties in mass-loss rates
Amedeo Romagnolo, Floor S. Broekgaarden, Konstantinos Antoniadis +1
Stellar winds are a major source of uncertainty in understanding the life and deaths of massive stars. Across studies in the field, prescriptions for stellar winds differ substanti…
