Updated Void Catalogs of the SDSS DR7 Main Sample

We produce several public void catalogs using a volume-limited subsample of the Sloan Digital Sky Survey Data Release 7 (SDSS DR7). Using new implementations three different void-finding algorithms, VoidFinder and two ZOBOV-based algorithms (VIDE REVOLVER), we identify 1163, 531, 518 cosmic voids with radii >10 Mpc/h, respectively, out to redshift z = 0.114 assuming Planck 2018 cosmology, 1184, 535, 519 WMAP5 cosmology. compute effective centers for all find none an radius >54 Mpc/h. The median is 15-19 Mpc/h algorithms. extract discuss properties populations, including radial density profiles, volume fraction catalog contained within voids, galaxies voids. 64 mock galaxy created from Horizon Run 4 N-body simulation, compare simulated observed good agreement between SDSS DR7 results.
