Resumen:
We analyse properties of galaxy groups and study their dependence on the large-scale environment, as dened by future virialized structures (FVS). We nd that groups within global large-scale overdensities have a larger stellar mass content, and a systematically older stellar population. The star formation rate and stellar mass prole of the groups residing in superstructures also di er from groups elsewhere. The combination of these e ects support an assembly bias scenario, indicating that groups in superstructures formed earlier. Also, the brightest group galaxies show greater di erences than less luminous galaxies.
