Fig. 16.


2–10 keV luminosity (observed-frame, absorbed) vs. redshift plot that shows the sensitivity limit of the XZ method for NH = 1023 (top panel), 1024 (middle panel) and 1025 (bottom panel) cm−2. In order to compare the response of XZ for different instruments, we normalize the luminosity values to 100 ks. Both current and future missions are shown; XZ is particularly sensitive to the upcoming mission Athena.
