Study On Long Period Photometric Analysis Of Blazar

Blazar is one of the research hotspots of modern astrophysics, developmentis very rapid, whether observed or theoretical research. Blazar is a special class ofgalaxies, which exists phenomenon of violent and intense physical process.Theradiation mechanism of Blazar research activities, energy production plays animportant role in our study of the universe. Study on the observed Blazar variabilitycan help us understand important properties of Blazar movement, Forexample,center structure, the mass of the black hole, radiation mechanism. Canalso help we understand the theoretical model of Blazar.This paper introduces the classification, Blazar radiation mechanism,theoretical model, and light. Then the active galactic nuclei of several calculationmethods of long period are introduced. For example, the structure function method,discrete correlation function, power spectrum, Jurkevich, and wavelet analysismethod.We use Period04software analysis the cycle of3C446and Mark1501. Wecollected a number of3C446Valid data points from the literature.We got the lightcurve, as can be seen from the curves, the objects have changed dramatically, but cannot see the celestial cycles from the curve.In this paper, using Period04cyclecalculation of celestial radio4.8GHz,8GHz,14GHz,22GHz data, found that thecycle for7.0years.Then we calculation and analysis to the black hole mass throughits cycle.
