The SAMI Galaxy Survey: observing the environmental quenching of star formation in GAMA groups

Schaefer, A. L.; Croom, Scott M.; Scott, Nicholas; Brough, Sarah; Allen, James T.; Bekki, Kenji; Bland-Hawthorn, J.; Bloom, J. V.; Bryant, J. J.; Cortese, L.; Federrath, Christoph; Groves, Brent Allan


We explore the radial distribution of star formation in galaxies in the SAMI Galaxy Survey as a function of their Local Group environment. Using a sample of galaxies in groups (with halo masses less than similar or equal to 10(14) M-circle dot) from the Galaxy And Mass Assembly Survey, we find signatures of environmental quenching in high-mass groups (M-G > 10(12.5) M-circle dot). The mean integrated specific star formation rate (sSFR) of star-forming galaxies in high-mass groups is lower than...[Show more]
