Blazar的長周期光變分析研究
[Abstract]:Blazar is the frontier of astrophysics, and the research of special theory and observation is developing rapidly. Blazar is one of the special galaxies, and there are violent phenomena and physical processes on it [1]. The study of the radiation flow and energy source of Blazar plays an important role in our study of the universe. In this paper, we study the phototropic energy of Blazar to explain the motion, intermediate structure, observational characteristics, brightness temperature, theoretical model and other important properties of Agalactic Nuclei (AGNs). The theoretical model of active galactic nuclei is also of great importance. This paper mainly introduces the classification, radiation mechanism, theoretical model and photovariation of AGN. Then, several methods of calculating long period of AGNs are introduced. For example, structural function method, DCF method, power spectrum, Jurkevich, and wavelet analysis. Period 4 software is used to analyze the cycle of 3C446 for the first time. We have collected a large number of effective data points of 3C446 in the literature and obtained the light variation curve. It can be seen from the curve that the object has a sharp change, but the long-period variation of the celestial body can not be seen from the curve. In this paper, Period04 software is used to calculate the periodicity of the celestial radio data of 4.8GHz (4.8GHz) ~ 8GHz ~ 8GHz ~ (14) GHz ~ (14) GHz. It is found that the period is 7.4 years. The mass and radiation region of black hole are calculated and studied by the results.
