Void detection in Stripe 82 eBOSS data

Description

Tomographic map of a quarter of Stripe 82 data (~ 0.25 Gpc^3). Map created with Lyman-alpha spectra from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS). Void finder is used on the map to create void catalog shown as light grey semi transparent spheroids. 1 isosurfaces in flux contrast (+0.14) is represented, which corresponds to underdensities in the cosmic web.
