Revealing distribution of galaxies in the Great Attractor region behind Milky Way

我们进行了37年的星系巡天。5平方米在低银河纬度（l<5度）的大吸引子区域，已经探测到4360个星系。在这个区域，存在着丰富的星系团，ABELL 3627和CIZA 1324。第5736章已经知道了我们没有发现任何像ABEL 3627或CIZA 1324这样的富星系团。7-5736在我们的调查。光度函数的比较表明，Ks~ 10等附近的星系数目明显增加。这一增强对应的质量约为1015太阳质量。这个值与最近基于HI或X射线观测的研究一致，但比大吸引子的原始质量小约10倍。

We carried out a galaxy survey for 37. 5 sq. degrees of the Great Attractor region in the low galactic latitude(l<5deg), and have detected 4360 galaxies. In this region, existence of rich clusters of galaxies, ABELL3627 and CIZA1324. 7-5736, are already known. We could not find any rich clusters like ABEL3627 or CIZA1324. 7-5736 in our survey. Comparison of luminosity function shows that obvious enhancement of number of galaxies around Ks～10mag. This enhancement corresponds to mass of～1015 solar mass. This value is consistent with recent studies based on HI or X-ray observation, but approximately 10 times smaller than original mass of Great Attractor.
