We adopt L-Galaxies2020, alongside with the updates introduced in Parente et al. (2023), to study the star formation and dust content of galaxies located in different regions of the cosmic web. Given the lack of a clear-cut definition of cosmic web environments, we adopt different algorithms to identify them (voids, walls, filaments, and nodes). The main result is that galaxies in less dense environments feature larger star formation and dust content up to a certain stellar mass, after which galaxy properties are quite insensitive to the environment. In particular, in massive galaxies differences among environments are milder due to the disc instability driven supermassive black hole (SMBH) growth implemented in the SAM, which makes galaxy quenching environment insensitive. Comparing the model predictions with SDSS and GAMA observations, the agreement is remarkably good. This highlights the importance of the in-situ SMBH growth, and emphasizes the power of studying galaxy evolution through the perspective of large-scale environments.
