利用加拿大-英国深亚毫米巡天（CUDSS）的850 μm图像研究了莱曼破裂星系（LBG）的亚毫米波性质。我们使用了三个LBG样本：两个来自加拿大-法国深场（CFDF）调查，覆盖CUDSS 14和CUDSS 03，一个来自Steidel和合作者也覆盖CUDSS 14。我们测量了两个CFDF LBG样品在~2 σ水平的平均通量，CUDSS 03为0.414 ± 0.263 mJy，CUDSS 14为0.382 ± 0.206 mJy，但Steidel等人的样品与零通量一致。据此，我们将莱曼断裂对850 μm背景的贡献上限设定为约20%。我们还测量了LBG和SCUBA源之间的交叉聚类。根据该测量结果，我们推断Steidel等人样品的大聚类幅度为r 0 = 11.5 ± 3.0 ± 3.0 h-1 Mpc（其中第一个误差为统计误差，第二个误差为系统误差），CFDF 14的r 0 = 4.5 ± 7.0 ± 5.0 h-1 Mpc，CFDF 03的r 0 = 7.5 ± 7.0 ± 5.0 h-1 Mpc。Steidel等人的样品，我们有最显着的聚类检测，也是三个样品中最大的，并已光谱证实红移
We have used 850 μm maps obtained as part of the Canada-UK Deep Submillimeter Survey (CUDSS) to investigate the submillimeter properties of Lyman break galaxies (LBGs). We used three samples of LBGs: two from the Canada-France Deep Fields (CFDF) survey covering CUDSS 14 and CUDSS 03, and one from Steidel and collaborators also covering CUDSS 14. We measure a mean flux from both CFDF LBG samples at a level of ~2 σ of 0.414 ± 0.263 mJy for CUDSS 03 and 0.382 ± 0.206 mJy for CUDSS 14, but the Steidel et al. sample is consistent with zero flux. From this we place upper limits on the Lyman break contribution to the 850 μm background of ~20%. We have also measured the cross-clustering between the LBGs and the SCUBA sources. From this measurement we infer a large clustering amplitude of r0 = 11.5 ± 3.0 ± 3.0 h-1 Mpc for the Steidel et al. sample (where the first error is statistical and the second systematic), r0 = 4.5 ± 7.0 ± 5.0 h-1 Mpc for CFDF 14, and r0 = 7.5 ± 7.0 ± 5.0 h-1 Mpc for CFDF 03. The Steidel et al. sample, for which we have the most significant detection of clustering, is also the largest of the three samples and has spectroscopically confirmed redshifts
