摘要：
We use the largest, most uniform, and most spectroscopically complete to faint X-ray flux limits Chandra sample to date to construct hard (2-8 keV) rest-frame X-ray luminosity functions (HXLFs) of spectroscopically identified active galactic nuclei (AGNs) to z similar to 5. In addition, we use a new 2-8 keV local sample selected by the very hard (14-195 keV) SWIFT 9-month Burst Alert Telescope survey to construct the local 2-8 keV HXLF. We do maximum likelihood fits of the combined distant plus local sample (as well as of the distant sample alone) over the redshift intervals 0 < z < 1.2, 0 < z < 3, and 0 < z < 5 using a variety of analytic forms, which we compare with the HXLFs. We recommend using our luminosity-dependent density evolution model fits of the combined distant plus local sample over 0 < z < 3 for all the spectroscopically identified sources and for the broad-line AGNs.
