Research Abstract |
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.
