【摘要】：本文先对活动星系核的特性、基本分类、产能机制及统一模型做了较为全面的综述,然后再对费米耀变体(Blazars)的一个子类费米平谱射电类星体(FSRQs)的外光子场和赛弗特1星系(Seyfert 1)的黑洞质量与宇宙学红移等问题进行的主要研究。第一章,主要介绍了活动星系核的一些基本特性,一般分类及各子类相应的性质,活动星系核的主要产能机制和统一模型;费米伽玛空间望远镜。第二章,介绍了费米耀变体(Blazars)的性质和辐射特性,以及赛弗特1星系的性质。第三章,我们对具有高效的吸积率产生强的外光子场的费米平谱射电类星体(FSRQs)进行研究,得到以下结论:(1)逆康普顿散射峰值光度和同步辐射峰值光度之比SICLL/与逆康普顿散射峰值频率和同步辐射峰值频率之比SIC??/呈现负相关性;(2)逆康普顿散射峰值光度与同步辐射峰值光度之间具有较强的相关性;(3)对于大多数的费米FSRQs天体,逆康普顿散射峰值光度大于同步辐射峰值光度。这些结果都表明费米平谱射电类星体的种子光子除了来源于宽线区以外,还可能来源于其它的区域。并且,喷流的运动与磁场及外光子的能量密度相关。第四章,我们对窄线Seyfert 1星系和宽线Seyfert 1星系的四个物理量(红移、爱丁顿比、黑洞质量和热光度)各自的分布进行了研究,并且还讨论了红移和热光度,红移和爱丁顿比之间的关系,得到如下结论:窄线Seyfert 1星系出现在宇宙演化的早期,并且其红移、热光度、爱丁顿比的平均值都比宽线Seyfert 1星系的平均值大,而黑洞质量的平均值比宽线Seyfert 1星系的平均值小,随着演化的发展,黑洞对周围物质的吸积作用不断增大,吸积能量不能维持其吸积过程,吸积率就慢慢下降,当演化进行到一定时,窄线Seyfert 1星系就过渡到了宽线Seyfert 1星系。
[Abstract]:In this paper, the characteristics, basic classification, productivity mechanism and unified model of AGNs are reviewed. Then the outer photon field and Seyfert 1 of a subclass of the Fermi plane radio quasar FSRQs of the Fermiyao variant Blazars) and the Seyfert 1). Of black hole mass and cosmological redshift. Chapter 1. This paper mainly introduces some basic characteristics of AGNs, general classification and corresponding properties of each subclass, main productivity mechanism and unified model of AGNs. The Fermi Gamma Space Telescope. Chapter 2 introduces the properties and radiation properties of the Fermiyao variant Blazars, as well as the properties of the Severt 1 galaxy. Chapter 3. We study the FSRQs of Fermipin-spectrum radio quasars with high accretion rate and strong external photon field. The ratio of the inverse Compton scattering peak luminosity to the synchrotron radiation peak luminosity / the ratio of the inverse Compton scattering peak frequency to the inverse Compton scattering peak frequency and the synchrotron radiation peak frequency is obtained. ? / negative correlation; (2) there is a strong correlation between the peak luminosity of inverse Compton scattering and the peak luminosity of synchrotron radiation; For most Fermi FSRQs objects. The inverse Compton scattering peak luminosity is greater than the synchrotron radiation peak luminosity. These results indicate that the seed photons of Fermiping spectrum radio quasars may come from other regions besides the wide line region. The motion of the jet is related to the magnetic field and the energy density of the outer photon. In Chapter 4th, we study the four physical quantities (redshift, Eddington ratio) of the narrow-line Seyfert _ 1 galaxy and the wide-line Seyfert _ 1 galaxy. The relationship between red shift and thermal luminosity, redshift and thermal luminosity, redshift and Eddington ratio are also discussed. The conclusions are as follows: the narrow-line Seyfert _ 1 galaxy appeared in the early stage of cosmic evolution, and its redshift, thermal luminosity, and Eddington ratio were larger than those of the wide-line Seyfert _ 1 galaxy. The mean mass of black hole is smaller than that of wide-line Seyfert _ 1 galaxy. With the development of evolution, the accretion effect of black hole on the surrounding matter is increasing, and accretion energy can not maintain its accretion process. The accretion rate decreases slowly, and as the evolution reaches a certain point, the narrow-line Seyfert _ 1 galaxy is transitioned to the wide-line Seyfert _ 1 galaxy.
