Abstract

The next generation of wide-field spectroscopic redshift surveys will map the large-scale galaxy distribution in the redshift range 0.7 ≤ z ≤ 2 to measure baryonic acoustic oscillations (BAO). The primary optical signature used in this redshift range comes from the [Oii] emission line doublet, which provides a unique redshift identification that can minimize confusion with other single emission lines. To derive the required spectrograph resolution for these redshift surveys, we simulate observations of the [Oii] (λλ 3727, 3729) doublet for various instrument resolutions, and line velocities. We foresee two strategies for the choice of the resolution for future spectrographs for BAO surveys. For bright [Oii] emitter surveys ([Oii] flux ~30 × 10-17 erg cm-2 s-1 like SDSS-IV/eBOSS), a resolution of R ~ 3300 allows the separation of 90 percent of the doublets. The impact of the sky lines on the completeness in redshift is less than 6 percent. For faint [Oii] emitter surveys ([Oii] flux ~10 × 10-17 erg cm-2 s-1 like DESi), the detection improves continuously with resolution, so we recommend the highest possible resolution, the limit being given by the number of pixels (4k by 4k) on the detector and the number of spectroscopic channels (2 or 3).

<front><div type="abstract" xml:lang="en">The next generation of wide-field spectroscopic redshift surveys will map the large-scale          galaxy distribution in the redshift range 0.7 ≤ z ≤ 2 to measure baryonic          acoustic oscillations (BAO). The primary optical signature used in this redshift range          comes from the [Oii] emission line doublet, which provides a unique redshift          identification that can minimize confusion with other single emission lines. To derive the          required spectrograph resolution for these redshift surveys, we simulate observations of          the [Oii] (λλ 3727, 3729) doublet for various instrument          resolutions, and line velocities. We foresee two strategies for the choice of the          resolution for future spectrographs for BAO surveys. For bright [Oii] emitter          surveys ([Oii] flux            ~30 × 10-17  erg   cm-2   s-1 like SDSS-IV/eBOSS), a          resolution of R ~ 3300 allows the separation of 90 percent of the          doublets. The impact of the sky lines on the completeness in redshift is less than 6          percent. For faint [Oii] emitter surveys ([Oii] flux            ~10 × 10-17  erg   cm-2   s-1 like DESi), the          detection improves continuously with resolution, so we recommend the highest possible          resolution, the limit being given by the number of pixels (4k by 4k) on the detector and          the number of spectroscopic channels (2 or 3).</div>
