论文摘要
Sloan数字天空调查（SDSS）条纹82中类星体的休息框紫外线/光学变异性用于测试Sun等人的Corona加热的积聚盘重新处理（CHAR）模型。 2020。我们采用我们的炭模型和观察到的黑洞质量（$ m _ {\ mathrm {bh}} $）和发光度（$ l $）来生成与真实观察相同的测量噪声和采样的模拟光曲线。没有任何微调，我们的char模型可以令人满意地重现不同$ m _ {\ mathrm {bh}} $，$ l $和REST-FRAME波长的观察到的集合结构功能。我们的分析表明，与紫外线/光发光性的恒定降压校正相比，依赖光度依赖性的隆重校正校正。我们的工作证明了通过将物理char模型与类星体光曲线进行比较，可以提取类星体性能（例如骨校正校正或无量纲粘度参数）的可能性。
The rest-frame UV/optical variability of the quasars in the Sloan Digital Sky Survey (SDSS) Stripe 82 is used to test the Corona-Heated Accretion-disk Reprocessing (CHAR) model of Sun et al. 2020. We adopt our CHAR model and the observed black-hole masses ($M_{\mathrm{BH}}$) and luminosities ($L$) to generate mock light curves that share the same measurement noise and sampling as the real observations. Without any fine-tuning, our CHAR model can satisfactorily reproduce the observed ensemble structure functions for different $M_{\mathrm{BH}}$, $L$, and rest-frame wavelengths. Our analyses reveal that a luminosity-dependent bolometric correction is disfavored over the constant bolometric correction for UV/optical luminosities. Our work demonstrates the possibility of extracting quasar properties (e.g., the bolometric correction or the dimensionless viscosity parameter) by comparing the physical CHAR model with quasar light curves.
