论文摘要

夏威夷调查场SSA22是Chandra X射线最深的第四大领域。为了对该领域进行最全面的探索,我们提供了来自Keck/Deimos和Keck/LRIS的新光谱,这些光谱与文献结合使用,将2---8 KEV样品的光谱完整性带到62%。我们还对没有光谱红移的来源进行光谱分类并估计光度光度。然后,我们确定了活性银核(AGN)的完整样品以及宽线AGN(blagns)和非爆炸的硬X射线光度函数(XLFS)。我们用于完整样本的XLF与文献非常吻合,在红移范围内显示出相对较强的演变,$ 0.25 \ le z <4 $。 blagns和非禁忌的XLF表示与红移的不同演变,在较高的红移和X射线亮度下,Blagns越来越占主导地位。

The Hawaii Survey Field SSA22 is the fourth deepest Chandra X-ray field. To allow for the fullest exploration of this field, we present new optical spectroscopy from Keck/DEIMOS and Keck/LRIS, which, in combination with the literature, brings the spectroscopic completeness of the 2--8 keV sample to 62%. We also make optical spectral classifications and estimate photometric redshifts for the sources without spectroscopic redshifts. We then determine hard X-ray luminosity functions (XLFs) for the full sample of Active Galactic Nuclei (AGNs), as well as for the broad-line AGNs (BLAGNs) and the non-BLAGNs separately. Our XLF for the full sample is in good agreement with the literature, showing relatively strong evolution over the redshift range $0.25\le z < 4$. The XLFs for the BLAGNs and the non-BLAGNs imply distinct evolution with redshift, with BLAGNs becoming increasingly dominant at higher redshifts and X-ray luminosities.
