Table 3
Merger rate density of BHNSs from Pop. III and Pop. II stars.
| Model | Population | RBHNS(z = 0) (Gpc−3 yr−1) | RBHNS(z = 13.2) (Gpc−3 yr−1) | RBHNS(z = 8.9) (Gpc−3 yr−1) |
|---|---|---|---|---|
| lar1 | Pop. III | 3.5 × 10−2 | 1.7 | 0.8 |
| kro1 | Pop. II | 0.2 | 6.5 | 13.7 |
Notes. Column 1: name of the model producing the largest MRD. In the case of Pop. II stars, only the fiducial model kro1 was considered. Column 2: stellar population. Column 3: MRD at z = 0. Column 4: MRD at the peak of the Pop. III distribution. Column 5: MRD at the peak of the Pop. II distribution.
