Void radial density profiles. For each of the seven SDSS/CAVITY nearby voids that are included in the CosmicFlows-3 volume, we show the radial number of galaxies in the left panel and the matter content in the right panel computed from CF3 (blue) and from the galaxy number density in SDSS (pink). All seven voids are empty of galaxies near their center and roughly up to their effective radius. However, four voids (474, 487, 727 and 738) display CF3-computed overdensities of matter in their center.
