【摘要】：在很多低/硬態(tài)X射線雙星系統(tǒng)(XRB)中,射電和X射線光度之間存在較好的相關(guān)關(guān)系.Dong等人通過研究得出了射電靜類星體(RQQ)也存在著這一關(guān)系,并且其關(guān)系式與低/硬態(tài)X射線雙星的基本面關(guān)系有著一定的相似度.分析收集的射電噪類星體來探究射電噪類星體是否也存在著這種關(guān)聯(lián),這些源包含了255個(gè)射電噪類星體.分析結(jié)果表明:(1)255個(gè)射電噪類星體(RLQ)的黑洞質(zhì)量與X射線和射電光度之間以及射電光度愛丁頓比率和X射線愛丁頓比率之間均存在相關(guān)性,這與Dong等人運(yùn)用亮硬態(tài)黑洞雙星和射電噪類星體所得出的基本面關(guān)系式有一定的相似性,但仍然存在一定差異.(2)低/硬態(tài)X射線雙星與射電噪類星體的基本面關(guān)系式可統(tǒng)一為lg L_R=0.998~(+0.045)_(-0.045)lg L_X+0.592~(+0.049)_(-0.049)lg M_(BH)-6.56~(+1.605)_(-1.605)(其中L_R為射電光度,L_X為X射線光度,M_(BH)為黑洞質(zhì)量).(3)研究結(jié)果進(jìn)一步證明了X射線和射電光度與黑洞質(zhì)量所構(gòu)成的基本面關(guān)系式具有高度的統(tǒng)一性,不僅可用于描述低/硬態(tài)X射線雙星系統(tǒng)和射電靜類星體,同樣可用于射電噪類星體.
[Abstract]:In many low / hard X-ray binary systems XRBs. There is a good correlation between radio and X-ray luminosity. Dong et al. Obtained the same relationship between radio static quasar RQQ). And its relationship has certain similarity with the fundamental relation of low / hard X-ray binary star. Analyze the collected radio noise quasars to find out whether the radio noise quasars also exist this correlation. These sources contain 255 radio noise quasars. The analytical results show that: 1) 255 radio noise quasars RLQ). There is a correlation between the mass of black hole and X-ray and radio luminosity, as well as between the radio luminosity Eddington ratio and X-ray Eddington ratio. This is similar to the fundamental equation obtained by Dong et al using bright hard black hole binaries and radio noise quasars. However, there is still some difference between low / hard X-ray binary stars and radio noise quasars. The basic relation formula can be unified as LG LRN 0.998 (0.045 / 0. 045). _ _ _. Among them, L _ S _ R was radio luminosity. The results of the study further prove that the fundamental relation between X-ray and radio luminosity and black hole mass has a high degree of unity. It can be used not only to describe low / hard X-ray binary systems and radio static quasars, but also to describe radio noise quasars.
