dual and offset AGN at high z

Redshift evolution of the number of dual and offset AGN

This figure is a follow-up of Steinborn et al. (2016), showing the redshift evolution of the number of dual and offset AGN in Magneticum.
The upper panel shows the number density of dual+offset AGN versus redshift. The lower panel shows the fraction of dual+offset AGN with respect to the total number of AGN, also versus redshift. We define all BHs with log_L>43 as an AGN. Dual and offset AGN are pairs of SMBHs within a co-moving distance of 10kpc.
