OPTX计划II：z<5活动星系核的硬X射线光度函数
The OPTX Project II: Hard X-ray Luminosity Functions of Active Galactic Nuclei for z<5
摘要：
我们使用迄今为止最大、最均匀、光谱上最完整到最微弱的X射线通量极限的Chandra样品，构造了z~5范围内光谱上确定的活动星系核（AGN）的2-8 keV静止坐标系X射线光度函数（HXLF）。此外，我们使用一个新的2-8 keV的本地样本选择非常硬（14-195 keV）SWIFT 9个月的爆发警报望远镜（BAT）的调查，以构建本地2-8 keV的HXLF。我们使用各种解析形式，在红移区间0<z<1.2，0<z<3，0<z<5上对组合的远地加本地样本（以及单独的远地样本）进行极大似然拟合，并与HXLF进行比较。我们推荐使用我们的光度依赖的密度演化（LDDE）模型拟合的组合远地加本地样本在0<z<3的所有光谱识别的源和宽线活动星系核。
英文摘要：
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~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 (BAT) 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 (LDDE) 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.
