The J-PAS survey: The effect of photometric redshift errors on cosmic voids

Open Access

Fig. 2.

Example of a void identified by ZOBOV. The void volume consists of Voronoi cells (red and cyan polygons) corresponding to its member galaxies (blue dots). The void contains 202 galaxies (and correspondingly consists of the same number of Voronoi cells) and encompasses a volume of about 2700 (Mpc/h)³. The minimum void density is $ρ_{\min} = 0.30 \bar{ρ}$ $\rho_{\mathrm{min}} = 0.30\,\bar{\rho}$ .
