我们对钱德拉深场北区 1 Ms 曝光中检测到的 370 个 X 射线源中的 135 个进行了亚毫米观测。其中九个 X 射线源的检测精度达到亚毫米级。误差加权平均 850 μm 通量在 1.21 ± 0.27 mJy 处显着。该值显示出对 5 × 10-16 至 10-14 ergs cm-2 s-1 的 2-8 keV 通量的依赖性很小，但具有比该值更亮的 X 射线通量的源在亚毫米级显得较弱。 X 射线源集合贡献了 850 μm 河外背景光的约 15%。亚毫米过量被发现在 20 厘米处可见的光学微弱 X 射线源中最强，这与这些 X 射线源被遮挡且处于高红移 (z > 1) 一致。
We present submillimeter observations for 135 of the 370 X-ray sources detected in the 1 Ms exposure of the Chandra Deep Field-North. Nine of the X-ray sources are significantly detected in the submillimeter. The error-weighted mean 850 μm flux is significant at 1.21 ± 0.27 mJy. This value shows little dependence on the 2-8 keV flux from 5 × 10-16 to 10-14 ergs cm-2 s-1, but sources with brighter X-ray fluxes than this appear weak in the submillimeter. The ensemble of X-ray sources contribute about 15% of the extragalactic background light at 850 μm. The submillimeter excess is found to be strongest in the optically faint X-ray sources that are also seen at 20 cm, which is consistent with these X-ray sources being obscured and at high redshift (z > 1).
