论文摘要
为了了解超质量黑洞与宿主星系的质量分布和共同进化，测量AGN的黑洞质量至关重要。混响映射是估计AGN中黑洞质量的独特工具。我们使用长期监测数据进行了光谱混响研究，并具有100多个无线电大声的类星体PKS 0736+017的光谱，以估计宽线区域（BLR）和黑洞质量的大小。光谱显示强大的H $ \MATHRMβ$和H $ \MATHRMγ$发射线。我们生成了5100Å连续通量（$ f_ {5100} $），H $β$和H $γ$的光曲线。所有光曲线都发现有很大的变化，分数可变性为69 $ \％$，21 $ \％$，30 $ \％$ \％$ $ \％$，H $β$和H $γ$光曲线。除热贡献外，非热发射有助于估计的5100Å的连续亮度。使用不同的方法，例如ccf，{\ small javelin}，von-Neumann，我们估计了BLR的大小，该大小的大小被认为是66.4 $^{+6.0} _ { - 4.2} $ light days在其余框架中。 BLR大小与H $β$的线宽相结合提供的黑洞质量为7.32 $^{+0.89} _ { - 0.91} \ times 10^{7} M _ {\ odot} $。来源紧随AGN的BLR尺寸亮度关系。
To understand the mass distribution and co-evolution of supermassive black holes with their host galaxy, it is crucial to measure the black hole mass of AGN. Reverberation mapping is a unique tool to estimate the black hole masses in AGN. We performed spectroscopic reverberation study using long-term monitoring data with more than 100 spectra of a radio-loud quasar PKS 0736+017 to estimate the size of the broad line region (BLR) and black hole mass. The optical spectrum shows strong H$\mathrmβ$ and H$\mathrmγ$ emission lines. We generated the light curves of 5100Å continuum flux ($f_{5100}$), H$β$, and H$γ$. All the light curves are found to be strongly variable with fractional variability of 69$\%$, 21$\%$, 30$\%$ for V-band, H$β$, and H$γ$ light curves, respectively. Along with the thermal contribution, non-thermal emission contributes to the estimated continuum luminosity at 5100Å. Using different methods, e.g., CCF, {\small JAVELIN}, von-neumann, we estimated the size of the BLR, which is found to be 66.4$^{+6.0}_{-4.2}$ light days in the rest frame. The BLR size combined with the line width of H$β$ provides a black hole mass of 7.32$^{+0.89}_{-0.91} \times 10^{7}M_{\odot}$. The source closely follows the BLR size-luminosity relation of AGN.
