Abstract

Separate fragments from the life of galaxies are considered. The motive uniting them is the component of dark matter. Using the hypothesis stated earlier about its origin and properties, the distribution of this component in galaxies and the influence it exerts on some galactic processes are analyzed. A comparison of the distribution of the dark component in elliptical and disk galaxies shows a higher concentration in elliptical galaxies. This conclusion follows from the relatively mature age of the stars in these galaxies and their chaotic motion. For this reason, in elliptical galaxies, the effect of radiation emission of a dark component outside the central zone decreases, which allows its particles to gather near the galactic core. For a quasar to appear in the center of a galaxy, some preparation is required. It represents both the accumulation of baryonic matter in the central body of the galaxy and near it, and the replenishment of the corresponding reserve of electromagnetic energy supplied by the dark component. In elliptical galaxies, the preparation for the quasar phase is faster compared to disk galaxies. In recent galaxies, the higher-frequency radiation of young stars has a greater resistance to the movement of dark component particles from the halo to the core. For the same reason, in disk galaxies, the particle formation rate of the dark component from intrinsic low-frequency radiation will be lower. It is concluded that after a series of cycles of utilization of galactic waste, accompanied by hydrogen regeneration, the life reserve of the galaxy decreases, and it gradually passes into the stage of slow extinction. But even in this state, a quasar appears in the core of the galaxy. Therefore, the situation is quite real when the underlying galaxy of a quasar can be invisible precisely because of faded stars, and not just because of the excessive brightness of the quasar itself. In addition, an almost extinct galaxy can capture a small young galaxy. The resources of a captured galaxy can contribute to the appearance of a quasar, giving the impression of its origin in a young and small galaxy. This explains the appearance of supermassive central objects in the forming galaxies, which cannot be explained in the Big Bang hypothesis. A possible mechanism of radio bursts is shown. They occur in galactic nuclei and are determined by the dark component of matter.
