The Dependence of Star Formation Rates on Stellar Mass and Environment at z~0.8

This plot shows recent results from Patel et al., who measured the
masses and SFRs of z~0.8 galaxies in a large field which includes a
cluster. The colored data points show the median mass and SFR of
galaxies in three different density bins, where the density is
calculated from the distance to the 7th-nearest neighbor. Galaxies in
higher densities have lower sSFRs, even at fixed mass. The black points
are values from Maaike's general field sample at similar redshifts.
