Abstract: Galaxy clusters are located at the nodes of the filamentary network known as the cosmic web. A more comprehensive understanding of galaxy clusters can be achieved by considering their environment, in particular, the filamentary structures to which they are connected. I analyse the simulated clusters of The300 simulations to study the impact of filaments on the galaxy clusters properties, such as their mass and dynamical state. Moreover, I assess the reliability of the cosmic web reconstruction from mock observational data. In particular, I first study the effect of 2D projection and rotation on the identification of gas filaments. Then, I analyse the filamentary network extracted from SZ and X-ray simulated maps, comparing it to that extracted from the gas distribution, and investigate the effects of instrumental features on the cosmic web identification.
