Filaments and clusters of the cosmic web have an impact on the properties of galaxies. They switch o ff their star-formation, contribute to the build-up of their stellar mass, and a ff ect the acquisition of their angular momentum. We make use of the IllustrisTNG simulation, coupled with the DisPerSE cosmic web extraction algorithm, to test which galaxy property is most a ff ected by the cosmic web and, conversely, to assess the di ff erential impact of the various cosmic web features on a given… 

sconce: a cosmic web finder for spherical and conic geometries.

A novel cosmic web identifier called sconce (Spherical and CONic Cosmic wEb finder) that inherently considers the 2D spherical or the 3D conic geometry, which is intrinsic to the spherical/conic geometry and invariant to data rotations is presented.
