Abstract
We study the effects of the environment on galaxy quenching in the outskirts of clusters of the spectroscopic survey OmegaWINGS ($0.04 < z < 0.08$).We use the OmegaWINGS galaxies clusters that are linkedto other groups/clusters by filaments, and study separately galaxies located in two regions in the outskirts of these clusters according to whether they are located towards the filaments' directionsor not.We find a fraction of passive galaxies in the outskirts of clusters intermediate between thatof the clusters and the field. We find evidence of a more effective quenching in thedirection of the filaments.We also analyse the abundance of post-starburst galaxies in the outskirts of clustersfocusing our study on two extreme set of galaxies according to their phase-space position:backsplash galaxies and true infaller galaxies.
