The Fundamental Plane Relationship Of Black Hole Activity For Strong Jet Radio Black Hole Sources

In recent years,the fundamental plane relationship of black hole activity has been one of the hot topics in astronomy.It naturally connects black holes of different scales(including stellar black holes and supermassive black holes).This implies that black holes of different scale may have similar physical properties,including similar central engines(black holes),similar accretion-jet coupling relationships,and so on.In general,most stellar black holes are observed in the form of black hole Xray binaries(BHXRB),which form accretion disk around their companion stars and generate multi-band radiation.The supermassive black holes(SMBH)are mainly located in the central region of galaxies.This article primarily elaborates through the following four chapters:In the first chapter,we introduce some essential characteristics of black holes of different scale at first,including the evolution of black hole X-ray binaries’ energy state and the classification of active galactic nuclei.Secondly,two different branches of radio-X-ray correlation and X-ray radiation mechanism are briefly introduced.Finally,we focus on several vital models in accretion physics,including the standard thin disk model(SSD),Advection-Dominated Accretion Flows(ADAF and Slim),and the energy extraction mechanism in the jet.In the second chapter,firstly,the classification of strong jet radio sources is determined.Then the theoretical equation of Doppler beaming effect is deduced.Finally,the difference of the Doppler factor in different energy bands is explained and the intrinsic radiation flow and luminosity of strong jet radio source are calculated.In the third chapter,we construct a sample including 23 Blazars and 15 FR Is to study the fundamental plane relationship of black hole activity in strong jet radio sources.The following results are obtained :(1)Their radio-X-ray correlation seems to follow an exceptional branch(?);(2)The slope of the fundamental plane relationship of black hole activity is steeper(ξ_X ~ 1.24),which means that X-rays come from jets;(3)The samples’ coverage roughly corresponds to the quiet state,low / hard state and bright hard state of black hole X-ray binaries.In the fourth chapter,our work and existing problems are summarized,and future work is prospected.
