摘要:

我们研究了黑洞活动的基本平面与红移和无线电响度在无线电响亮和无线电安静类星体人口的相关性。源汇编从档案数据的无线电大声和无线电安静类星体的红移$0.1 < z < 5.0$产生一个样本的353个源与已知的X射线,无线电,和黑洞质量测量。一个基本的吸积活动平面适合于射电强和射电静类星体的样本,我们发现射电强和射电静源之间的二分法。最好地描述这两个样本的最佳拟合方程组是针对我们的无线电大声样本的$\log{L_{R}} = (1.12 \pm 0.06) \log{L_{X}} - (0.20 \pm 0.07) \log{M} -(5.64 \pm 2.99)$和针对我们的无线电安静样本的$\log{L_{R}} = (0.48 \pm 0.06) \log{L_{X}} + (0.50 \pm 0.08) \log{M} + (15.26 \pm 2.66)$。我们的研究结果表明,平均射电安静类星体的发射是一致的平流为主的吸积,而喷流和光盘的组合发射占主导地位的射电响亮类星体。我们还研究了红移的趋势之间的无线电大声和无线电安静的样本,我们观察到的红移依赖的基本平面的无线电大声类星体。最后,我们利用基本平面作为一个黑洞质量估计方法,并确定它有用的研究系统的标准光谱建模技术是不可行的。

英文摘要:

We examine the fundamental plane of black hole activity for correlations with redshift and radio loudness in both radio-loud and radio-quiet quasar populations. Sources are compiled from archival data of both radio-loud and radio-quiet quasars over redshifts $0.1 < z < 5.0$ to produce a sample of 353 sources with known X-ray, radio, and black hole mass measurements. A fundamental plane of accretion activity is fit to a sample of radio-loud and radio-quiet quasars, and we find a dichotomy between radio-loud and radio-quiet sources. The set of best-fit equations that best describe the two samples are $\log{L_{R}} = (1.12 \pm 0.06) \log{L_{X}} - (0.20 \pm 0.07) \log{M} -(5.64 \pm 2.99)$ for our radio-loud sample and $\log{L_{R}} = (0.48 \pm 0.06) \log{L_{X}} + (0.50 \pm 0.08) \log{M} + (15.26 \pm 2.66)$ for our radio-quiet sample. Our results suggest that the average radio-quiet quasar emission is consistent with advection dominated accretion, while a combination of jet and disc emission dominates in radio-loud quasars. We additionally examine redshift trends amongst the radio-loud and radio-quiet samples, and we observe a redshift dependence for the fundamental plane of radio-loud quasars. Lastly, we utilize the fundamental plane as a black hole mass estimation method and determine it useful in studying systems where standard spectral modeling techniques are not viable.
