摘要
我们呈现了 Euclid 快速发布（Q1）天区中候选活动星系核（AGN）的星表。对于每个 Euclid 源，我们收集了来自 Galaxy Evolution Explorer（GALEX）、、暗能量巡天（DES）、Wise-field 红外巡天探测器（WISE）、、暗能量巡天（DESI）和斯隆数字巡天（SDSS）的多波段测光和光谱信息，包括来自公共汇编的光谱红移。我们通过使用 Euclid 颜色和 WISE-AllWISE 截断值应用选源标准来调查 Q1 天区的 AGN 内容，分别找到了 292 222 和 65 131 个候选体。我们还基于 DR3 信息创建了一个高纯度 QSO 星表，包含 1 971 个候选体。此外，我们利用从 DESI 收集的光谱信息进行了宽线和窄线 AGN 选源，在 Q1 天区共得到 4 392 个 AGN 候选体。我们调查并优化了 Q1 概率随机森林 QSO 群体，共选出 180 666 个候选体。此外，我们对具有可用 的源子集进行了 SED 拟合，并通过利用推导的 AGN 比例，共识别了 7 766 个 AGN 候选体。我们讨论了选源的纯度和完备性，并定义了两个新的颜色选源标准（ 和 ）以提高纯度，分别在 Q1 数据中找到 313 714 和 267 513 个候选体。我们共找到 229 779 个 AGN 候选体，对应 的 AGN 面密度为 3 641 deg，当限制深度为 时，对应一个 30 422 个候选体的子样本，AGN 面密度为 482 deg。本工作中恢复的 AGN 面密度与基于 AGN X 射线光度函数的预测一致。
