我们提出的统计红移分布的一个大样本的低表面亮度（LSB）的星系中确定的第一个200 deg 2的超Suprime-Cam战略调查计划。通过与NASA-SDSS图集的互相关，我们发现大部分天体都位于z 108 M以内，LSB星系没有形成高表面亮度星系的质量-尺寸关系的平滑延伸，这可能表明LSB星系的形成路径是不同的。
We present the statistical redshift distribution of a large sample of low-surface-brightness (LSB) galaxies identified in the first 200 deg2 of the Hyper Suprime-Cam Strategic Survey Program. Through cross-correlation with the NASA–SDSS Atlas, we find that the majority of objects lie within z 108 M ⊙), the LSB galaxies do not form a smooth extension of the mass–size relation of higher-surface-brightness galaxies, perhaps suggesting that the LSB galaxy population is distinct in its formation path.
