Cumulative distribution functions (CDFs) of the kNN distances for a volume-limited AGN sample in the low-redshift range (0.01 < z < 0.03, dashed lines) and higher-redshift range (0.03 < z < 0.06, solid lines). The top plot shows the CDFs as a function of angular distance, while the bottom plot shows the corresponding physical projected separation assuming the average redshift of each z−bin. AGN in the lower redshift range have closer galactic neighbors than AGN in the higher redshift range due to the 2MRS flux limit.
