Several recent observations using large data sets of galaxies showed non-random distribution of the spin directions of spiral galaxies, even when the galaxies are too far from each other to have gravitational interaction. Here, a data set of $\sim8.7\cdot10^3$ spiral galaxies imaged by Hubble Space Telescope (HST) is used to test and profile a possible asymmetry between galaxy spin directions. The asymmetry between galaxies with opposite spin directions is compared to the asymmetry of galaxies from the Sloan Digital Sky Survey. The two data sets contain different galaxies at different redshift ranges, and each data set was annotated using a different annotation method. The results show that both data sets show a similar asymmetry in the COSMOS field, which is covered by both telescopes. Fitting the asymmetry of the galaxies to cosine dependence shows a dipole axis with probabilities of $\sim2.8\sigma$ and $\sim7.38\sigma$ in HST and SDSS, respectively. The most likely dipole axis identified in the HST galaxies is at $(\alpha=78^{\rm o},\delta=47^{\rm o})$ and is well within the $1\sigma$ error range compared to the location of the most likely dipole axis in the SDSS galaxies with $z>0.15$ , identified at $(\alpha=71^{\rm o},\delta=61^{\rm o})$ .

HST和SDSS中的星系自旋方向分布表现出类似的大尺度不对称性

最近使用大型星系数据集进行的几项观测表明，螺旋星系的自旋方向是非随机分布的，即使星系彼此相距太远而无法进行引力相互作用也是如此。这里，一个数据集 $\sim8.7\cdot10^3$ 螺旋星系成像哈勃太空望远镜(高铁) 用于测试和描绘星系自旋方向之间可能的不对称性。具有相反自旋方向的星系之间的不对称性与斯隆数字巡天中星系的不对称性进行了比较。这两个数据集包含不同红移范围的不同星系，并且每个数据集都使用不同的注释方法进行了注释。结果表明，两个数据集在两个望远镜都覆盖的 COSMOS 场中显示出类似的不对称性。将星系的不对称性与余弦相关性拟合显示偶极轴，其概率为 $\sim2.8\sigma$ 和 $\sim7.38\sigma$ 在高铁和SDSS，分别。中确定的最可能的偶极轴高铁星系在 $(\alpha=78^{\rm o},\delta=47^{\rm o})$ 并且在 $1\sigma$ 与SDSS星系中最可能的偶极轴位置相比的误差范围 $z>0.15$ , 确定于 $(\alpha=71^{\rm o},\delta=61^{\rm o})$ .
