PopSyCLE simulation parameters.
| Parameter | Value |
|---|---|
| Milky Way escape velocity | 550 kms−1 (Piffl et al. 2014) |
| Sun-Galactic Center distance | 8.3 kpc |
| Mean BH natal kick | 100 kms−1 |
| Mean NS natal kick | {150 kms−1, 250 kms−1, 350 kms−1, 450 kms−1} |
| Initial–final mass relation (IFMR) | SukhboldN20 (Sukhbold & Woosley 2014; Sukhbold et al. 2016; Woosley 2017; Woosley et al. 2020) |
| Extinction law | Damineli et al. (2016) |
| Bar dimensions (radius, major axis, minor axis, height) | (2.54, 0.70, 0.424, 0.424) kpc |
| Bar angle (Sun–Galactic Center, 2nd, 3rd) | (62.0, 3.5, 91.3)° |
| Bulge velocity dispersion (radial, azimuthal, z) | (100, 100, 100) kms−1 |
| Bar pattern speed | 40.00 kms−1 kpc−1 |
| Multiplicity | Singles |
Notes. The implementation of the IFMR is described in detail in Rose et al. (2022); the Galactic parameters are consistent with “v3” in Lam et al. (2020, Appendix A). We ran four simulations differing by NS natal kick distributions.
