【摘要】：活動星系在天文學(xué)上,是一類特殊的星系,它的核心稱為活動星系核(active galactic nuclei,AGN),Blazars是活動星系核中最為活躍的一個子類,它具有高光度、快速大幅光變、高偏振、視超光速運(yùn)動、噴流指向觀測等奇異的觀測現(xiàn)象和極端的物理特征。blazars的奇特性質(zhì)反映出其結(jié)構(gòu)和物理過程都十分復(fù)雜,本文主要對Fermi耀變體噴流吸積的關(guān)系、質(zhì)光關(guān)系、多波段輻射、吸積率以及黑洞質(zhì)量等問題進(jìn)行一系列的研究。首先,對活動星系核的概念,分類,模型做了簡單的介紹,對目前活動星系核的黑洞質(zhì)量、多波段輻射和噴流做了相關(guān)的介紹。其次,介紹了耀變體(blazar)的觀測特性、輻射機(jī)制,并簡單的介紹了Fermi衛(wèi)星以及Fermi源。另外,我們從文獻(xiàn)中搜集到了111個Fermi耀變體(73個FSRQ,38個BL Lac),得到了可靠的射電核光度、寬線區(qū)光度、熱光度和黑洞質(zhì)量。我們的研究結(jié)果表明射電核光度和寬線區(qū)光度之間有明顯的相關(guān),支持了吸積過程和相對論噴流之間有緊密的聯(lián)系。分析得到的關(guān)系~(0.81?0.06)C BLR RLogL L跟理論模型預(yù)測的結(jié)果一致,支持了耀變體噴流功率來源于從快速旋轉(zhuǎn)的克爾黑洞中提取能量,吸積盤的磁場導(dǎo)致了黑洞的旋轉(zhuǎn)。通過研究黑洞質(zhì)量和內(nèi)稟的熱光度之間的關(guān)系,支持了Fermi耀變體的質(zhì)量—光度關(guān)系是冪律的,類似于主序星。接下來,討論了耀變體的演化序列。最后,從文獻(xiàn)中搜集了191個Fermi FSRQ樣本,我們研究了該樣本吸積率和多波段光度之間的關(guān)系,黑洞質(zhì)量和多波段光度之間的關(guān)系,得到如下結(jié)果:吸積率和多波段光度之間有顯著的相關(guān)性,支持了噴流的形成和吸積之間有緊密的聯(lián)系。黑洞質(zhì)量和多波段光度之間的顯著相關(guān)性可能暗示著更快速的噴流和更大質(zhì)量的黑洞之間有緊密的聯(lián)系。
[Abstract]:Active galaxies are a special class of galaxies in astronomy, whose core is called the (active galactic nuclei AGN) Blazars, one of the most active subclasses of AGNs, which has high luminosity, rapid and large light changes, high polarization, and hypervelocity of light. The strange observation phenomena such as jet pointing observation and extreme physical characteristics. The peculiar properties of blazars reflect the complexity of its structure and physical process. This paper mainly deals with the relationship between jet accretion, mass light relation and multiband radiation. Accretion rate and black hole mass are studied. Firstly, the concept, classification and model of AGNs are briefly introduced, and the mass of black holes, multi-band radiation and jets of AGNs are introduced. Secondly, the observational characteristics and radiation mechanism of (blazar) are introduced, and the Fermi satellite and Fermi source are briefly introduced. In addition, 111 Fermi eau variants (73 FSRQs and 38 BL Lac),) have been collected from the literature to obtain reliable radio nuclear luminosity, wide-line luminosity, thermal luminosity and black hole mass. Our results show that there is an obvious correlation between radio nucleus luminosity and wide-line luminosity, which supports the close relationship between accretion process and relativistic jet. The analysis results of the relation ~ (0.81n) 0.06) C BLR RLogL L are consistent with the theoretical model, which supports that the power of the glowing body jet is derived from the rapidly rotating Kerr black hole, and the magnetic field of the accretion disk leads to the rotation of the black hole. By studying the relationship between black hole mass and intrinsic thermal luminosity, it is supported that the mass-luminosity relationship of Fermi's yaw is a power law, similar to that of a principal ordered star. Next, the evolutionary sequence of the yaw variant is discussed. Finally, 191 Fermi FSRQ samples were collected from the literature. We studied the relationship between accretion rate and multiband luminosity, black hole mass and multiband luminosity. The results are as follows: there is a significant correlation between accretion rate and multiband luminosity, which supports a close relationship between jet formation and accretion. The significant correlation between black hole mass and multispectral luminosity may suggest a close relationship between faster jet and larger mass black hole.
