【摘要】：本文主要对活动星系核(AGN)的超大黑洞质量、多波段辐射特性、射电噪类星体(RLQs)和射电宁静类星体(RQQs)之间的关系、窄线Seyfert1星系(NLS1s)和宽线Seyfert1星系(BLS1s)之间的关系、高能伽马射线的辐射机制、喷流和吸积盘之间的关系、演化等问题进行了一系列的研究。第一章，简单介绍了活动星系核的基本概念、分类、模型；目前活动星系核黑洞质量的主要估算方法；多波段辐射特性；Fermi伽马空间望远镜；甚高能伽马射线；AGN伽马射线辐射机制。第二章，收集了117个类星体(97个射电噪类星体(RLQs)和20个射电宁静类星体(RQQs))的热光度、H发射线宽度、射电光学强度比R、5100的单色光度、红移，并且计算了黑洞质量、爱丁顿比、总的5GHz射电光度。得到如下结论：(1)RLQs的黑洞质量和射电光学强度比R、射电光度、热光度之间具有强的相关性，而RQQs的黑洞质量和射电光学强度比R、射电光度、热光度之间具有弱的相关性；(2)RLQs的射电光度、热光度、5100的单色光度之间具有强的相关性，而RQQs的射电光度、热光度、5100的单色光度之间具有弱的相关性；(3)RLQs和RQQs的黑洞质量、发射线宽度、爱丁顿比不同；从这些结果中可以得到：RLQs和RQQs黑洞质量的不同可能是由于它们发射线宽度不同造成的；RLQs和RQQs本质不同很可能是它们内秉物理性质不同引起的；黑洞质量、爱丁顿比、寄主星系的形态、黑洞自旋是解释双峰状分布和射电光学强度比R的重要参量；射电喷流和吸积盘之间具有紧密的联系。第三章，收集了142个类星体(114个射电噪类星体和28个射电宁静类星体)，82个瓣占优型射电类星体(LDQ)和43个核占优型射电类星体(CDQ)，80个Seyfert星系的样本，基于Logistic非线性回归分析的方法对红移和黑洞质量、热光度、5GHz射电光度、爱丁顿比、核主导参数的关系进行研究。拟合出相应的演化曲线。得到如下结论：(1)类星体的演化是从射电噪类星体到射电宁静类星体，当演化到一定阶段类星体过渡到Seyfert星系；(2)瓣占优型类星体(LDQ)和核占优型类星体(CDQ)之间并没有明显地随红移演化。第四章，从斯隆数字巡天(SDSS)中收集了214个Seyfert1星系包括147个窄线Seyfert1星系(NLS1s)和67个宽线Seyfert1星系(BLS1s)。对两类Seyfert1星系的黑洞质量、核球速度弥散度、爱丁顿比、红移、5100光度进行了研究。得到：(1)在进行黑洞质量估算时，应该考虑辐射压的影响，特别是对于窄线Seyfert1星系(NLS1s)；(2)当考虑辐射压时，窄线Seyfert1星系(NLS1s)的吸积未超爱丁顿吸积，并且满足了近距正常星系的M BH关系；(3)验证了从窄线Seyfert1星系(NLS1s)到宽线Seyfert1星系(BLS1s)的演化。第五章，通过对TeV活动星系核Fermi伽马射线和多波段辐射的研究，我们得到：(1)对于TeV HSP BL Lacs(THBLs)，在所有的态(高态、平均态、低态)下，F和FR之间，F和FI R之间具有强的相关性；(2)TeV射电星系(TRGs)偏离了THBLs所占的区域；(3)和THBLs相比，TeV平谱射电类星体(TFSRQs)有更强的γ射线辐射；(4)对于THBLs，在所有态下，F和FX之间有弱的相关性，，并且在高态和平均态，F和FO有弱的相关性，在低态下F和FO有强的相关性；(5)对于THBLs，低态和高态的FO和FR之间，所有态的FO和FI R之间，所以态的FIR和FR之间存在强的相关性，其它波段之间没有发现强的相关性；(6)对于THBLs，同步自康普顿(SSC)是主要的高能γ射线辐射机制，并且逆康普顿(IC)散射核周围的尘埃很可能是个重要的补充机制；(7)和THBLs相比，TRGs和TFSRQs可能有不同的高能γ射线起源。第六章，通过对Fermi平谱射电类星体(FSRQs)宽发射线光度和多波段光度的研究。我们得到：对于FSRQs，log L和log LBLR之间，log LX和log LBLR之间，log LO和log LBLR之间，log LR和log LBLR之间有显著的相关性；log LIR和log LBLR之间的相关性不显著(P0.08)，但可以认为有显著相关的“趋势”。这些结果支持了喷流的形成和吸积盘之间有紧密的联系。并且log L和log LBLR之间的显著相关暗示了FSRQs的伽马射线的辐射机制是逆康普顿散射来自宽线区(BLR)或外流BLR的种子光子。
[Abstract]:In this paper , the relationship between large black hole mass , multi - band radiation characteristic , radio - noise quasar ( RLQs ) and radio quiet quasar ( RQQs ) of active galactic nuclei ( AGN ) is studied .

In chapter one , the basic concept , classification and model of active galactic nuclei are briefly introduced .
The main methods of estimating the quality of the nuclear black holes in active galaxies are presented .
Multi - band radiation characteristics ;
Fermi - gamma space telescope
very high energy gamma rays ;
AGN Gamma Ray Radiation Mechanism .

In chapter 2 , 117 quasars ( 97 radio noise quasars ( RLQs ) and 20 radio silent quasars ( RQQs ) are collected , the widths of H emission lines , the ratio of the radio intensity to the monochromatic light of R and 5100 , the red shift are calculated , and the black hole quality , the Edinburgh ratio and the total 5 GHz radio luminosity are calculated . The following conclusions are obtained : ( 1 ) The black hole quality and the radio optical intensity ratio R , the radio luminosity and the thermal luminosity of the RLQs have strong correlation , while the black hole quality and the radio optical intensity ratio R , the radio luminosity and the thermal luminosity of the RQQs have weak correlation ;
( 2 ) there is a strong correlation between the radio luminosity , the thermal luminosity and the monochromatic light intensity of the RLQs , while the RQQs have a weak correlation between the radio luminosity , the thermal luminosity and the monochromatic light intensity of 5100 .
( 3 ) The quality of black holes , the width of the emission lines and the ratio of Edinburgh to RLQs and RQQs are different ;
From these results , it can be found that the differences in the quality of RLQs and RQQs black holes may be due to the different widths of their transmission lines ;
RLQs and RQQs are different in nature and may be caused by different intrinsic physical properties ;
The black hole mass , the Edinburgh ratio , the shape of the host galaxy , the spin of the black hole are important parameters for explaining the bimodal distribution and the radio - optical intensity ratio R ;
there is a close relationship between the radio jet and the accretion disk .

In chapter 3 , we collected 142 quasars ( 114 radio noise quasars and 28 radio silent quasars ) , 82 lobes dominant radio - quasars ( LDQ ) and 43 nuclear - dominant radio - quasars ( CDQ ) , and investigated the relationship between red shift and black hole mass , thermal luminosity , 5 GHz radio luminosity , Edinburgh ratio and nuclear dominant parameters based on Logistic non - linear regression analysis .
( 2 ) There is no obvious evolution of the red shift between the lobe - dominated quasar ( LDQ ) and the nuclear - dominated quasar ( CDQ ) .

In chapter 4 , we collected 214 galaxies from the Slong Digital Tour ( SDSS ) , including 147 narrow lines ( NLS1s ) and 67 broad - lines ( BLS1s ) galaxies . We studied the black hole quality , the velocity dispersion of the nuclear sphere , the ratio of Edinburgh , red shift , 5100 luminosity to the two types of galaxies .
( 2 ) When considering the radiation pressure , the accretion of the narrow - line Sefert1 galaxy ( NLS1s ) is not super - Edinburgh accretion , and the M - BH relation of the close - range normal galaxy is satisfied ;
( 3 ) The evolution of the galaxy ( NLS1s ) from the narrow line to the wide line of galaxies ( BLS1s ) is verified .

In the fifth chapter , we obtain : ( 1 ) For TeV HSP BL Lacs , we obtain : ( 1 ) There is strong correlation between F and FR between F and FR in all states ( high , average and low states ) for TeV HSP BL Lacs ( THallop ) .
( 2 ) The TeV radio galaxy ( TRGs ) deviates from the region occupied by THECK ;
( 3 ) The TeV flat - spectrum radio - quasar ( TFSRQs ) has stronger 纬 - ray radiation than that of THB .
( 4 ) In all states , there is a weak correlation between F and FX in all states , and F and FO are strongly correlated in high and average states , and F and FO are strongly correlated in low states ;
( 5 ) There is strong correlation between the FO and FRs of all states , and there is strong correlation between the states ' FIR and FR , and there is no strong correlation between the other bands .
( 6 ) The synchronous self - compton ( SSC ) is the main high - energy 纬 - ray radiation mechanism , and the dust around the scattering core of the inverse compton ( IC ) is probably an important supplementary mechanism .
( 7 ) TRGs and TFSRQs may have different origins of high - energy 纬 - ray compared with THEC2 .

In chapter 6 , we obtain the correlation between log L and log LBLR , log LO and log LBLR , log LR and log LBLR between log LX and log LBLR for FSRQs , log L and log LBLR .
The correlation between log LIR and log LBLR is not significant ( P0 . 08 ) , but it may be considered a significant correlation " trend " . These results support a close link between the formation of the jet and the accretion disk , and the significant correlation between log L and log LBLR implies that the radiation mechanism of the gamma rays of the FSRQs is the seed photons scattered from the wide line region ( BLR ) or the outer stream BLR .
