Fluxes and velocities for the Hβ and [O III] λλ4959,5007 galaxy line components from fits to the quasar-subtracted spectra presented in Figure 4, which have been integrated over the three emission-line regions shown in Figure 3.
| FHβ | F[O III] λ4959 | F[O III] λ5007 | F[O III] λ5007/FHβ | Vr | Vσ | |
|---|---|---|---|---|---|---|
| (10−18 erg/s/cm2) [S/N] | (km/s) | |||||
| Region 1 (Host) | < 2.1 | 2.3 ± 0.6 [4.1] | 6.8 ± 0.6 [12] | > 3.2 | 0 (z = 7.0804) | 86 ± 49 |
| Region 2 (Companion) | 0.4 ± 0.1 [3.6] | 2.3 ± 0.2 [12] | 6.8 ± 0.1 [55] | 16.4 ± 4.6 | 30 ± 49 | 104 ± 49 |
| Region 3 | < 0.4 | 0.8 ± 0.1 [8.2] | 2.5 ± 0.1 [23] | > 7.0 | 143 ± 49 | 83 ± 49 |
Notes. The values in braces give the integrated S/N of each line. Upper limits for undetected lines are 3σ limits on the line flux. The velocity Vr is relative to the redshift of the quasar host, obtained from the integrated spectrum of Region 1, z = 7.0804 ± 0.0028. Uncertainties on the velocity and velocity dispersion (Vσ) assume an uncertainty of ±1 wavelength element, ±6.65 Å or 49 km/s. The velocity dispersions have been corrected for an instrumental broadening of FWHMinst = 115 km/s. The fluxes of these extended sources have not been multiplied by the aperture correction.
