Mitigating the impact of fiber assignment on clustering measurements from deep galaxy redshift surveys

Understand

We examine the impact of fiber assignment on clustering measurements from fiber-fed spectroscopic galaxy surveys.

• We identify new effects which were absent in previous, relatively shallow galaxy surveys such as Baryon Oscillation Spectroscopic Survey .
• Specifically, we consider deep surveys covering a wide redshift range from z=0.6 to z=2.4, as in the Subaru Prime Focus Spectrograph survey.
• Such surveys will have more target galaxies than we can place fibers on.
