摘要
星际团队光(ICL)渗透星系团是星系团组装历史的标志性物探针，亦可能是其暗物质结构的标志。本工作探讨Euclid宽广调查检测ICL的能力。我们模拟了覆盖红移范围(0.3-1.8)和撞击质量( M)的星系团，基于观察antly激发的ICL模型。我们识别出围绕最亮星系团星系(BCG)的50-200 kpc圆形环形区域ICL信噪比(S/N)最大化，并以该孔径内的S/N作为ICL检测的图谱性能指标。我们比较了三种最先进的ICL检测方法，发现执行高表面亮度源遮蔽后简单孔径光度测量的方法能够对质量超过 M的星系团实现最小偏差的ICL检测。ICL检测的S/N主要受红移限制，这由宇宙暗淡效应导致，而非星系团质量。假设ICL包含恒星光的15%，我们预测Euclid将在z=0.3至1.5之间检测质量超过 M的约8万个星系团ICL，S/N>3。其中一半的星系团位于z<0.75以下，大多数位于z<0.6的星系团可实现S/N>20。少数数千个位于z=1.3至1.5的星系团的ICL可被检测到S/N>3。ICL模型的表面亮度轮廓对星系团质量和观测红移均强烈依赖，因此ICL的外缘最适于观测质量超过 M的最具代表性的星系团。Euclid将在其大尺度调查范围内探测到距离BCG超过500 kpc的ICL，最高可达z=0.7，在数百个代表性星系团中实现。
