摘要
本研究探索了欧几里得快速数据发布(Q1)中罕见源种群的区域，这些区域目前处于光谱红移空间的未被探索区域，旨在为即将到来的光谱研究提供支持。我们的目标是识别并研究以高度离子化发射线为特征的源种群，这些发射线指示活跃性核活动、极端冲击现象或伍尔-雷特星。对光谱进行全面的人工检查，以确保样本的可靠性，聚焦同时检测到NeV和OII发射线 measurements 的条件，将欧几里得光谱红移范围限制在z=2.48--3.88。为了 characterize 这一人口，我们分析了其宿主星系的形态-光谱光度属性。这允许与表现相似OII性质和光谱红移但不具NeV线的对照源进行直接比较。我们仅基于光谱标准识别位于Halpha限度之外的源。该样本包含65个潜在NeV候选者，提供了对这些NeV候选者在高红移处的系统性探针。我们发现，在直接积分和高斯拟合方法计算的光谱测量值之间，存在良好的1σ一致性。NeV候选者的颜色类似于明亮QSO，仅有少数位于非常红色的尾部。我们观察到更高的恒星质量、4000A断口处的较低连续光谱，以及与对照样本相似的Sérsic指数分布。这个独特的样本为广泛的科学调查铺平了道路，后续数据发布将进一步 pursue。
