On the relative effect of nodes and filaments of the cosmic web on the
  quenching of galaxies and the orientation of their spin
  Filaments and clusters of the cosmic web have an impact on the properties of
galaxies, switching off their star-formation, contributing to the build-up of
their stellar mass, and influencing the acquisition of their angular momentum.
In this work we make use of the IllustrisTNG simulation, coupled with the
DisPerSE cosmic web extraction algorithm, to test which is the galaxy property
most affected by the cosmic web and, conversely, to assess the differential
impact of the various cosmic web features on a given galaxy property. Our aim
is to use this information to better understand galaxy evolution and to
identify on which galaxy property future efforts should focus to detect the
cosmic web from the galaxy distribution. We provide a comprehensive analysis of
the relation between galaxy properties and cosmic web features. We also perform
extensive tests in which we try to disentangle the effect of local
overdensities of galaxies on their properties from the effect of the large
scale structure environment. Our results show that star-formation is the
quantity that shows the strongest variation with the distances from the cosmic
web features, but it is also the one that shows the strongest relation to the
local environment of galaxies. On the other hand, the direction of the angular
momentum of galaxies is the property that shows the weakest trends with
distance from cosmic web features, while also being more independent from the
local environment of galaxies. We conclude that the direction of the angular
momentum of galaxies and its use to improve our detection of the cosmic web
features could be the focus of futures studies benefiting from larger
statistical samples.
