A Strongly Parametrized Mass Ratio Model for the Stable Mass Transfer Channel: a Case Study of the Peak
Jaxen Godfrey, Lieke van Son, Ben Farr
The mass ratio of merging binary black holes (BBHs) carries information about their formation history, yet has received less attention than masses, spins and eccentricities as a ch…

Evidence of the pair instability gap from black hole masses
Hui Tong, Maya Fishbach, Eric Thrane +13
Stellar theory predicts a forbidden range of black-hole masses between -- due to pair-instability supernovae, but evidence for such a gap in the mass distri…
