Description
Recent spectroscopic and photometric studies at low and intermediate redshifts (e.g. SDSS, GAMA, VIPERS, COSMOS, etc) have shown evidence that either proximity to cosmic filaments, or the number of filaments a group/cluster is connected to, modulates galaxy mass assembly (mass, star-formation rate, spin) beyond the mere effect of halo mass and local density. I will briefly review some of these results and sketch possible interpretations. In particular, based on our recent measurements from hydrodynamical simulations, I will present a quenching mechanism directly related to the high angular momentum supply in galaxies lying at the vorticity-rich edge of cosmic filaments. I will briefly discuss how we expect future spectroscopic surveys to shed new light on this particular topic.
