Popis: Understanding the morphological and dynamical evolution of galaxies across cosmic time is one of the key goals of modern extragalactic astrophysics. Our current view is that galaxies are objects that evolve secularly and build their stellar mass through star formation which is sustained by cold gas accretion from the cosmic web. However, this picture is not sufficient to explain entirely their evolution. Environmental processes can also affect their morphology, kinematics, or gas content, as well as quench star formation, and can thus be driving mechanisms to explain the transition from high to low redshift. Thus, important recent efforts have been put into probing the effect of the environment on galaxies. In this endeavour, 3D spectroscopy can help because it provides spatially resolved properties across the galaxies' extent. MUSE is one of the most powerful 3D spectrographs thanks to its large field-of-view and high sensitivity when combined with adaptive optics. During this Thesis, I have used data from the deep MUSE-gAlaxy Groups In Cosmos survey (MAGIC) which targets galaxy groups/clusters in the COSMOS field, as well as foreground and background field galaxies. MAGIC is ideal to probe the impact of the environment at 0.2
