在过去的三十年中，使用莱曼断裂技术进行的光度星系选择改变了我们对高 z 宇宙的理解，提供了污染相对较小的大量星系样本。随着JWST的出现，莱曼断裂技术现已扩展到z∼17。然而，所得样品的纯度尚未经过测试。在这里，我们使用一个建立在暗物质晕质量函数的坚实基础上的简单模型，来表明预期的污染水平急剧上升，特别是对于发光星系来说，这对选择过程提出了严格的要求。最亮的光源可能比潜在污染物至少稀有 10000 倍，因此可能需要进行广泛的光谱后续活动来识别少量目标源。
Over the last three decades, photometric galaxy selection using the Lyman-break technique has transformed our understanding of the high-zUniverse, providing large samples of galaxies atwith relatively small contamination. With the advent of theJWST, the Lyman-break technique has now been extended toz∼ 17. However, the purity of the resulting samples has not been tested. Here, we use a simple model, built on the robust foundation of the dark matter halo mass function, to show that the expected level of contamination rises dramatically at, especially for luminous galaxies, placing stringent requirements on the selection process. The most luminous sources atare likely at least 10 000 times rarer than potential contaminants, so extensive spectroscopic follow-up campaigns may be required to identify a small number of target sources.
