Studies of the NGC315 galaxy and the distribution of extragalactic objects around it

Abstract

Studies of extended extragalactic radio sources have an important feature and significance for forming an opinion about the distribution of matter in the Universe. The galaxy NGC 315 is an extended radio source within which there are many compact radio sources that form its intensity. Studies of this galaxy and its surroundings assume that although there are many sources in the NGC 315 immediate vicinity, in its wider 6° circumferences, there is a deficiency of extragalactic sources, and this deficiency is more clearly expressed at distances between 0.8 and 2.2 redshifts. Considering the distribution of extragalactic sources in this region, we can state that this does not give grounds to consider the distribution in the Universe to be uniform, which indicates the heterogeneity of the Universe, although some doubts remain here. To solve this problem, it is necessary to carry out non-standard, more sensitive, and targeted multi-frequency observations, which will allow obtaining such results that will make the identification of the obtained multi-frequency data more reliable. One of the possible promising directions for solving this problem is, in particular, the possibility of using microchannel plates (MCPs) as radiation detectors, the technology of which has begun to develop rapidly in recent years.
