Fig. 7
Histogram of the redshift distribution of the brightest (J< 20 mag) optically resolved and unresolved Chandra X-ray detected quasars in the COSMOS field, respectively. At redshifts below z ≲ 1 the incompleteness of our parent sample due to morphology is most severe, while at z> 1 the unresolved population of quasars is representative of the full population.
