Active quasar fraction as a function of primary black hole mass at a median redshift of z ∼ 6.8 (second column), and total number of quasar counterparts over a redshift interval 6 < z < 7.1 (third column) expected inside the SKA localization ellipse, assuming a logarithmic mass interval of dlog10MBH = 0.1 around its central value.
| MBH | factive (η = 0.5) | Ngw, QSO (in 70 deg−2) |
|---|---|---|
| 109 M⊙ | 6.8 × 10−5 | ∼7 − 45 |
| 1010 M⊙ | 1.3 × 10−4 | ≲1 |
