摘要
活动星系核（AGN）关键性质（如吸积率、质量或自旋）的统计分布与演化仍是天体物理学中悬而未决的争论。欧洲空间局（ESA）的 Euclid 空间任务于 2023 年 7 月 1 日发射，有望在该领域实现突破。我们创建了详细的 AGN 光谱模拟星表，从静止系近红外到紫外，包含发射线，以模拟 Euclid 对遮蔽（2 型）与未遮蔽（1 型）AGN 的观测。我们聚焦于 NISP 仪器的红色光栅，其将用于广域巡天，为近红外光谱 AGN 研究开启新窗口。我们量化了红移测定效率以及 H+[NII] 复合体发射线流量的恢复效率，因为 Euclid 主要关注该发射线，预期其在所探测红移范围内最亮。在 H+[NII] 可见的区间内（0.89<z<1.83，线流量 erg s cm，涵盖 处 AGN 活动峰值），红色光栅光谱覆盖范围内 83% 的模拟 AGN 获得了光谱红移。在此红移范围外，测量效率显著下降。总体而言，对于 2 型 AGN 直至发射线流量 erg s cm，以及 1 型 AGN 直至 erg s cm，约 90% 正确确定了光谱红移。恢复的黑洞质量值与输入值有约 10% 的小偏移，但总体一致性良好。凭借 z<2 如此高的光谱覆盖率，我们将能够基于均一的光谱信息，对数十万 AGN 从 AGN 活动峰值时期到当今宇宙测量其人口统计、标度关系与成团性。
