eBOSS Lya line-of-sights in the Stripe 82

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). 2 isosurfaces in flux contrast are represented, which correspond to overdensities (-0.2 in red) and underdensities (0.2 in blue) in the cosmic web. The Lyman-alpha line-of-sights used to create the map are pictured by black lines. For more details, see https://arxiv.org/abs/2004.01448
