Monthly Notices of the Royal Astronomical Society, 491(3), 4294–43091365-2966https://doi.org/10.1093/mnras/stz3319http://hdl.handle.net/10566/5914We investigate the impact of the number of filaments connected to the nodes of the cosmic web on the physical properties of their galaxies using the Sloan Digital Sky Survey. We compare these measurements to the cosmological hydrodynamical simulations H ORIZON-(NO)AGN and SIMBA. We find that more massive galaxies are more connected, in qualitative agreement with theoretical predictions and measurements in dark-matter-only simulations. The star formation activity and morphology of observed galaxies both display some dependence on the connectivity of the cosmic web at a fixed stellar mass: Less star forming and less rotation supported galaxies also tend to have higher connectivity.enSurveysGalaxies: formationLarge-scale structure of UniverseGalaxies at its nodesConnectivityArticle
