Las estrechas relaciones existentes entre parámetros fundamentales de galaxias, tanto espirales como elípticas, son un reflejo de su formación y evolución. Concretamente, la relación de Tully-Fisher y el Plano Fundamental son un indicativo de la relación existente entre la masa total y la masa luminosa de las galaxias. Ambas relaciones han sido de

This thesis was devoted to the study of clusters and superclusters of galaxies. In particular, those that show a detectable Sunyaev-Zeldovich (SZ) effect. We aimed to fully characterize these structures and the relative contributions that their physical components (diffuse and collapsed phases) play in building up the total Sunyaev-Zeldovich signal

Dwarf galaxies have been the crossroad of significant theoretical and observational efforts, but we still lack firm constraints concerning their formation and evolution. They are also fundamental laboratories to investigate the impact of the environment on star formation and on chemical evolution in stellar systems that are order of magnitudes
