Research On Black Hole Spin, Jet And Fundamental

In this paper, we study a series of main problems including the relation between redshift of AGN and black hole spin energy, the correlation between black hole spin and jet power, the relation between the accretion rate and the jet power, the correlation between black hole spin and jet power, the correlation of jet power with black hole mass and spin in adio loud quasars, the fundamental plane of radio loud quasar AGNs and X-ray Binaries.In chapter 1, we briefly introduce the basic features of AGNs, for example, the classification and unification of AGNs; the estimated method of black hole mass for AGNs; the polarization, jet and accretion for AGNs; and the space Telescope of Fermi gamma-ray.In chapter 2, The balck holes in the hearts of galaxies and galaxy clusters are commonly observed to be associated with powerful relativistic jets. In this chapter we do the the correlation analysis between accretion rate and jet power. It is very helpful for our study the inter black hole and the form of jet. And also give the basic theory for the relation between black hole spin and jet.In chapter 3, we study the relation between redshiftof Blazar and black hole spin. The results are as following:(1) The Blazar blak hole spin have correlation with redshift in the three different in three different manmagnetic field strengths(B BEDD,B 10 G,B∝j);(2) FR II quasars,FR II radio loud quasars and FR II central dominant galaxies have different coefficient of correlation;(3)The results suggest that the black hole spin energy can reflect the information of accretion.In chapter 4, we study the relationship between black hole spin and radio loudness for radio loud AGN. The results are as following:(1) We find a significant correlation between black hole spin and radio loudness for SSRQs and FSRQs in three different manmagnetic field strengths(B BEDD,B 10 G,B∝j), which suggests a direct tight connection between black hole spin and radio loudness.;(2) The effect of relativistic beaming can be eliminated in this paper can for thecorrelation black hole spin and radio loudness;(3)Compared with SSRQs, FSRQs have no correlation between black hole spin and radio loudness, which suggests that the correlation have relation to the type of radio loud AGN.(4) The results is just the same as otherresults obtained in different ways which suggest that the black hole spin energy can reflect the information of accretion.In chapter 5,Supermassive black holes ususlly can be described by their mass and spin. The correlation analysis between black hole spin and jet power is very important for our study with black hole. Our conclusions are as follows:(1)There is a strong correlationbetween the black hole mass an jet power which has already been proved by other;(2) By analysing the data which we have colleted, the black hole spin truely has a strong correlation with jet power especially when the magnetic field strengths B BEDD;(3) There are a little difference between the two black hole spin of FlatSpectrum Radio Quasar’s and SteepSpectrum RadioQuasar’s distribution;(4)The results in this chapter, which is consistent with previous results, suggest that the black hole jet may get the energy from spin energy.In chapter 6,There are several low/hard state of X-ray binaries(XRBs) that follow an outliers’ s track of radio-X-ray correlation LR L and b 1.4) which has been found in recent years. There is a plane which is givenby black hole mass and the radio/X-ray luminosities in the space. In this chapter, we compiled a sample of radio loud active galactic nuclei(AGNs) and we also have found that the hard X-ray photon indies and Eddington raties of our sample are positively correlated. It is just like XRBs. The Eddington-scaled radio-X-ray correlation of our sample also have that of ’outliers’. A radiatively efficient accretion flow can regulate the positively correlated X-ray spectral evolution and the steeper radio-X-raycorrelation. Basedon these similarities,we can present a fundamental plane for outliers Several XRBs and Radio-loud quasars with blackhole(BH)mass, radio and X-ray luminosity. Thefundamental planeis logLR0.998. logLX0.592. logMBH6.56.. The plane can be suitable for the RLQ black hole sources. And the found relation also can be agreed by X-ray binaries.
