We investigate how environment affects satellite galaxies using theirlocation within the projected phase-space of their host haloes from the Wang etal.'s group catalogue. Using the Yonsei Zoom in Cluster Simulations, we derivezones of constant mean infall time T_inf in projected phase-space, andcatalogue in which zone each observed galaxy falls. Within each zone we computethe mean observed galaxy properties including specific star formation rate,luminosity-weighted age, stellar metallicity and [alpha/Fe] abundance ratio. Bycomparing galaxies in different zones, we inspect how shifting the mean infalltime from recent infallers (mean T_inf < 3 Gyr) to ancient infallers (meanT_inf > 5 Gyr) impacts galaxy properties at fixed stellar and halo mass.Ancient infallers are more quenched, and the impact of environmental quenchingis visible down to low host masses (< group masses). Meanwhile, the quenchingof recent infallers is weakly dependent on host mass, indicating they have yetto respond strongly to their current environment. [alpha/Fe] and especiallymetallicity are less dependent on host mass, but show a dependence on meanT_inf. We discuss these results in the context of longer exposure times forancient infallers to environmental effects, which grow more efficient in hostswith a deeper potential well and a denser intracluster medium. We also compareour satellites with a control field sample, and find that even the most recentinfallers (mean T_inf < 2 Gyr) are more quenched than field galaxies, inparticular for cluster mass hosts. This supports the role of pre-processingand/or faster quenching in satellites.
