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…

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…

Not just winds: why models find binary black hole formation is metallicity dependent, while binary neutron star formation is not
L. A. C. van Son, S. K. Roy, I. Mandel +6
Both detailed and rapid population studies alike predict that binary black hole (BHBH) formation is orders of magnitude more efficient at low metallicity than high metallicity, whi…
