Welcome to the Public Cosmic Void Catalog
This is the repository for the public releases of a comprehensive cosmic void catalog from galaxy redshift surveys and simulations. This catalog is the product of a collaboration of P.M. Sutter (IAP/OSU), Benjamin Wandelt (IAP/UPMC/Illinois), Guilhem Lavaux (Perimeter), and David Weinberg (OSU), with contributions from Nico Hamaus (IAP) and Alice Pisani (IAP). Our void finder algorithm is based on ZOBOV, which uses Voronoi tessellations and the watershed transform to identify voids. See here for the journal article describing our method used for defining and cataloging voids.
You can download the latest version of VIDE, our void finding code, here.
Have new void science ideas or interested in collaborating with us to gain access to pre-release catalogs and mock data sets? Just contact us!
