Study On Mass And Multi - Band Radiation Characteristics Of Super - Black Hole In Active Galaxy

In this thesis, we present the studies of the super black hole mass, the propertiesof multi-wave band emission, the relation between radio loud quasars (RLQs) andradio quiet quasars (RQQs), the relation between narrow line Seyfert1galaxies(NLS1s) and broad line Seyfert1galaxies (BLS1s), the radiation mechanism of highenengy gamma ray, the relation between jet and accretion, and evolution.In chapter1, we briefly introduce the basic conception, class and model ofactive galactic nuclei (AGN), the estimate of black hole mass, the properties ofmulti-wave band emission, Fermi satellite, gamma ray of very high energy (VHE)and the radiation mechanism of high enengy gamma ray of AGN.In chapter2, we collect the bolometric luminosity, full-width at half maximun(FWHM) of H, radio loudness R, monochromatic luminosity at5100and redshiftof117quasars (97radio loud quasars and20radio quiet quasars). Then we calculatethe black hole mass, Eddington ratio and total5GHz radio luminosity. Ourconclusions are as follows:(1)there are strong correlations between black hole massand radio loudness R, between black hole mass and radio luminosity and betweenblack hole mass and bolometric luminosity for radio loud quasars (RLQs), whereasweak correlations between black hole mass and radio loudness R, between black holemass and radio luminosity, between black hole mass and bolometric luminosity forradio quiet quasars (RQQs);(2)there are strong correlations between bolometricluminosity and monochromatic luminosity at5100, between bolometric luminosityand radio luminosity for RLQs, whereas weak correlations between bolometricluminosity and monochromatic luminosity at5100, between bolometric luminosityand radio luminosity for RQQs;(3)the black hole mass, FWHM and Eddington ratiobetween RQQs and RLQs are different. From these results, we suggest that thedifference in FWHM between RQQs and RLQs can cause the difference in black holemass between them; the difference between RQQs and RLQs is not due to differenceof orientation, but difference of intrinsic property; the black hole mass, Eddingtonratio, morphology of host galaxy and spin of black hole play an important role in explaining the origin of radio loudness and the radio loudness“bimodality”; there is aclose link between radio jet and disk accretion.In chapter3, we have collected142quasars (114radio loud quasars and28radio quiet quasars),82lobe-dominated quasars,43core-dominated quasars and80Seyfer galaxies. We analyse the relations among redshift, black hole mass, bolometricluminosity,5GHz radio luminosity, Eddington ratio and core-dominated parameter,and simulate the corresponding evolution curves from Logistic regression analysis.Our conclusions are follows：(1)the evolution of quasars are from radio loud quasarsto radio quiet quasars, and when it reach a certain stage, the transition is from quasarsto Seyfert galaxy;(2)for core-dominated quasars and lobe-dominated quasars, thereare no obvious evolution with redshift.In chapter4, we collect214Seyfert1galaxies (147narrow line Seyfert1galaxies and67broad line Seyfert1galaxies) and study black hole mass, bulgevelocity dispersion, Eddington radio, redshift and the luminosity at5100of them.Our conclusions are as follows:(1)when computing black hole mass, we shouldconsider the effect of radiation pressure, especially for the narrow line Seyfert1galaxies;(2)when considering the effect of radiation pressure, narrow line Seyfert1galaxies are in sub-Eddington accretion and meet MBH-relation of normal galaxies;(2)confirming the evolution of Seyfert1galaxies are from narrow line Seyfert1galaxies (NLS1s) to broad line Seyfert1galaxies (BLS1s).In chapter5, Using gamma-ray data detected by Fermi Large Area Telescope(LAT) and multi-wave band data for TeV active galactic nuclei (AGNs), we havestudied the correlations between flux densities (FR, FIR, FO, FXand Fγ) in the radio,infrared, optical, X-ray and gamma-ray wave bands. Our results are the following:(1)for TeV HSP BL Lacertae objects (THBLs), there are strong correlations betweenFγand FRand between Fγand FIRin all states (average/high/low);(2)the TeV radiogalaxies (TRGs) deviate from the area occupied by THBLs;(3)the TeV flat-spectrumradio quasars (TFSRQs) have much stronger gamma-ray emission than THBLs;(4)for THBLs, there are weak correlations between Fγand FXin all states as well asbetween Fγand FOin both average and high states, and a strong correlation betweenFγand FOin the low state;(5)for THBLs, there are strong correlations between FO and FRin both low and average states as well as between FOand FIRin all states andbetween FIRand FRin all states, but no strong correlations among other bands arefound. From these results, we suggest that for THBLs, the synchrotron self-Comptonradiation (SSC) is the main mechanism of high energy gamma-ray emission and theinverse Compton scattering of circum-nuclear dust is likely to be a importantcomplementary mechanism. Compared with THBLs, TRGs and TFSRQs may have adifferent origin of high energy gamma-ray.In chaper6, we study broad line and multi-wave luminosity relations forflat-spectrum radio quasars (FSRQs) detected by Fermi LAT. Our results are asfollows: for FSRQs, the correlations between logLγand logLBLR, between logLXandlogLBLR, between logLOand logLBLR, between logLRand logLBLRare significant; thecorrelation between logLIRand logLBLR(P=0.08) is not significant, but might berefereed as a “trend”of significant correlation. These results support a close linkbetween jet formation and accretion disk, and the Lγ-LBLRcorrelation suggests thatthe radiation mechanism of the gamma-ray emission in FSRQs is likely to be inverseCompton scattering of seed photons from BLR or outflowing BLR.
