Primary (M₁) and secondary (M₂) BH mass distribution of observable dynamically formed BBHs within our LG-like volume. Red dots show the estimated median values of the most massive GW events (M₁ > 50 M₀) detected by the LVK collaboration up to O4a, with error bars representing the 90% credible intervals. Dashed lines in histograms display the mass distributions of all BBH mergers that occur in our simulation.
