Distributions of stellar mass (left) and SSFR (right) of BGGs split into local high-density and low-density values. The BGGs in our analysis were split based on the mean value of the sample, with the orange line denoting high-density distributions and the blue line low-density distributions. The p-value of a KS-test on each pair of distributions is shown below the legend of each panel. BGG properties are strongly connected to their local densities.
