【摘要】： 在1974年,Fanaro?和Riley首次提出根據(jù)射電星系在178MHz處的光度和射電形態(tài),可以將射電星系分為兩類,即Fanaro?-Riley type Is(FRIs)和Fanaro?-Riley typeIIs(FRIIs),且FRIs的光度要小于FRIIs的。自此之后,人們一直致力于分析這兩類星系的本質(zhì)。目前除了經(jīng)典方法,還有多種方法可以區(qū)分Fanaro?-Riley星系。本文將從光學(xué)譜指數(shù)和X波段的光度研究兩類射電星系的性質(zhì),為此收集了一個大的樣本,并由此研究了光學(xué)譜指數(shù)、X光度及能譜分布。 第一章介紹了射電星系的相關(guān)性質(zhì)及其結(jié)構(gòu)。綜述了人們對于Fanaro?-Riley星系分類的研究。 第二章我們從光學(xué)數(shù)據(jù)出發(fā),計算了光學(xué)譜指數(shù)。比較FRIs和FRIIs光學(xué)譜指數(shù)的分布,發(fā)現(xiàn)FRIs的平均光學(xué)譜指數(shù)要大于FRIIs,
[Abstract]:In 1974, Fanaro? And Riley proposed for the first time that radio galaxies can be classified into two categories, Fanaro3, according to their luminosity and radio morphology at 178 MHz. Riley type Isa FRIsa and Fanaro? Since then, people have been trying to analyze the nature of these two kinds of galaxies. Besides the classical method, there are many ways to distinguish between the two kinds of galaxies. In this paper, we will study the properties of two kinds of radio galaxies in terms of optical spectral index and X-band luminosity. A large sample is collected for this purpose, and the optical spectral exponent X photometry and energy spectrum distribution are also studied. Chapter 1 introduces the properties and structure of radio galaxies. A study of the classification of Riley galaxies. In the second chapter, we calculate the optical spectral index from optical data. Compared with the distribution of FRIs and FRIIs optical spectral index, we find that the average optical spectral index of FRIs is larger than that of FRI Isa.
