I will present the results from our recent studies that aim to unveil the role of the cosmic web on the evolution of galaxies, focusing on the COSMOS field. We use a mass complete sample of galaxies with accurate photometric redshifts in the COSMOS field to construct the density field and the cosmic web to z=1.2, but I will also focus on an unique structure studied spectroscopically at z=0.84. The comic web extraction relies on the density field and breaks the density field into clusters, filaments, and the field. We show that at z0.8, the trend flattens out for the overall galaxy population and satellites. For star-forming (SF) galaxies only, the median SFR is constant at z>0.5 but declines by from the field to clusters for satellites and centrals at z0.5. We suggest that most satellites experience a rapid quenching mechanism as they fall from the field into clusters through filaments, whereas centrals mostly undergo a slow environmental quenching at z0.5 and a fast mechanism at higher redshifts. Our results highlight the importance of the large-scale cosmic web on galaxy evolution.
