Distribution of spectroscopic redshifts around the CC0958+0158 overdensity (see text). The gray and black histograms show the distribution within 600 and 2000 kpc, respectively. The inset shows the spatial distribution around the overdensity center of galaxies within Δz ~ 0.1 (or Δz ~ 0.2, smaller symbols) of the three spikes at z ~ 2.17, 2.19, 2.44, as indicated. The three gray circles have radii of 0.5, 1, 2 Mpc proper.
