Abstract: The paper describes the insides - the basic concepts of the Math Microscope, demonstrates the results of Super-Resolution images obtained from the Event Horizon Telescope and analyzes the results of the movement of clusters of stars that go around the Black Hole. The presence of point objects - single stars in the SR image allowed us to implement a... Show More

Abstract: We present statistical results from a sample of 91,006 Seyfert galaxies obtained from SDSS DR14 (Sloan Digital Sky Survey Data Release 14). Using the ratio of the flux of doubly ionized oxygen [OIII] to that of the flux of hydrogen beta line H_β, the Seyfert galaxy sample was separated into Seyferts 1 and 2. For each class of Seyfert galaxy, both bo... Show More
