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

我们进行了一次37年的星系调查。5平方英尺在低银河系纬度的大吸引区(L和lt；5度)，并已探测到4,360个星系。在这个区域，存在丰富的星系团，ABELL3627和CIZA1324。7-5736是已知的。我们找不到任何像ABEL3627或CIZA1324这样的丰富星系团。7-5736在我们的调查中。光度函数的比较表明，在Ks~10mag附近星系数目明显增加。这一增强相当于约1015个太阳质量。这个值与最近基于HI或X射线观测的研究一致，但大约比大吸引子的原始质量小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.
