Comparison of the local merger rate densities of BH-BH and NS-NS mergers from all our models (see Table 3) with the current limits inferred from the O1/O2 LIGO/Virgo observational runs: 9.7−101 Gpc⁻³ yr⁻¹ for the BH-BH mergers and 110−3840 Gpc⁻³ yr⁻¹ for the NS-NS events (Abbott et al. 2019b). Models that are consistent with the observational limits: M13.A, M23.A, M33.A, M43.A, M30.B, M40.B, M60.B, M70.B. We note that while some of the models are consistent with the observational constraints and others are not, it is not straightforward to draw conclusions about the physical ingredients of the models at this stage due to degeneracies in the impact of various assumptions on the theoretical merger rates (see Sect. 4.3.1).
