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 dier from groups elsewhere. The combination of these eects support an assembly bias scenario, indicating that groups in superstructures formed earlier. Also, the brightest group galaxies show greater dierences than less luminous galaxies.
