AEGIS-X：中央生长带的深钱德拉成像
AEGIS-X: Deep Chandra imaging of the Central Groth Strip
摘要：
我们介绍了扩展Groth带中心区域的深度\chandra成像结果，即AEGIS-X深度（AEGIS-XD）调查。当与之前对更宽区域的条带AEGIS-X Wide（AEGIS-XW; Laird等人，2009）的\chandra \观测结果相结合时，这些数据提供了三个中心ACIS-I场中800 ks标称暴露深度的数据，该区域约为$0.29$ ~deg $^{2}$。这是目前存在的第三个最深的X射线调查，比钱德拉深场（CDF）浅$\sim 2-3$，但面积比每个CDF大$\sim 3$倍。本文给出了在深\chandra观测中探测到的937个点源的目录。我们提出了我们的X射线源从深地面，斯皮策，GALEX和HST成像识别。利用似然比分析，我们对929/937个X射线源的多波段对应物进行了关联，估计可靠性为95%，使识别完整性在统计意义上约为94%。我们的353个X射线源的可靠光谱红移主要由Keck（DEEP 2/3）和MMT Hectospec提供，因此目前的光谱完整性为$\sim 38$ ~ %。我们计算光度红移的基础上，多波段光度学在多达35个波段，从紫外到中红外。特别注意的是，绝大多数的X-射线源是活动星系核，需要混合模板。我们的测光红移的平均精度为$σ=0.04$，异常值分数约为5%，达到$σ=0.03$，在坎德尔覆盖的区域内异常值小于4%。X射线、多波长测光和红移星表已公开提供。
英文摘要：
We present the results of deep \chandra\ imaging of the central region of the Extended Groth Strip, the AEGIS-X Deep (AEGIS-XD) survey. When combined with previous \chandra\ observations of a wider area of the strip, AEGIS-X Wide (AEGIS-XW; Laird et~al. 2009), these provide data to a nominal exposure depth of 800ks in the three central ACIS-I fields, a region of approximately $0.29$~deg$^{2}$. This is currently the third deepest X-ray survey in existence, a factor $\sim 2-3$ shallower than the Chandra Deep Fields (CDFs) but over an area $\sim 3$ times greater than each CDF. We present a catalogue of 937 point sources detected in the deep \chandra\ observations. We present identifications of our X-ray sources from deep ground-based, Spitzer, GALEX and HST imaging. Using a likelihood ratio analysis, we associate multi band counterparts for 929/937 of our X-ray sources, with an estimated 95~\% reliability, making the identification completeness approximately 94~\% in a statistical sense. Reliable spectroscopic redshifts for 353 of our X-ray sources are provided predominantly from Keck (DEEP2/3) and MMT Hectospec, so the current spectroscopic completeness is $\sim 38$~per cent. For the remainder of the X-ray sources, we compute photometric redshifts based on multi-band photometry in up to 35 bands from the UV to mid-IR. Particular attention is given to the fact that the vast majority the X-ray sources are AGN and require hybrid templates. Our photometric redshifts have mean accuracy of $σ=0.04$ and an outlier fraction of approximately 5\%, reaching $σ=0.03$ with less than 4\% outliers in the area covered by CANDELS . The X-ray, multi-wavelength photometry and redshift catalogues are made publicly available.
