论文摘要
我们研究了SDSS J110511.15+530806.5远处的类星体(Z = 1.929)在SLOAN数字天空调查在光学目录的数据版本7中获得的异常深吸收的起源。我们的目的是估计吸收材料的速度,我们表明,通过使用常见的病毒质量估计器,这种材料会严重影响我们对大型类星体中黑洞(BH)质量的测量。假设吸积盘发射受热的电晕,温暖的皮肤和靠近核的吸收材料的影响,则对类星体的光谱形状进行了建模。整个分析是使用XSPEC模型和工具进行的。总光谱形状用Agnsed模型表示,而深度吸收由两个高斯人很好地描述。观察到的频谱和拟合程序使我们能够估计类星体中的BH质量为$ 3.52 \ pm 0.01 \ times 10^9 m _ {\ odot} $,非零的BH旋转为$ a_* = 0.32 \ pm 0.04 $,并且增载率为$ \ dot $ \ dot m = 0.274 $ \ pm = 0.274 $ \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm \ pm。检测到的吸收剂的速度在6330-108135 km/s的范围内。当我们认为吸收是由胸腔引起的,一个吸收剂朝着核折叠的速度为73887 km/s。我们得出了约20300 km/s的BI指数,质量流出率高达源吸积率的38.5%。 SDSS J110511.15+530806.5在SDSS中观察到的高吸收是快风的证据,这些迹象将源置于与UFO(超快速流出)接壤的对象组中,强大的宽吸收线(BAL),强大的失败失败辐射辐射加速的尘土飞散(Frado)。与病毒质量估计相比,这种吸收通过两个数量级影响BH质量测量。
We study the origin of the anomalous deep absorption in a spectrum of the SDSS J110511.15+530806.5 distant quasar (z=1.929) obtained by the Sloan Digital Sky Survey in Data Release 7 of the optical catalog. We aim to estimate the velocity of absorbing material, and we show that this material considerably affects our measurements of the black hole (BH) mass in massive quasars with the use of common virial mass estimators. The spectral shape of the quasar was modeled assuming that the accretion disk emission is influenced by a hot corona, warm skin, and absorbing material located close to the nucleus. The whole analysis was undertaken with XSPEC models and tools. The overall spectral shape was represented with the AGNSED model, while the deep absorption is well described by two Gaussians. The observed spectrum and the fitting procedure allowed us to estimate the BH mass in the quasar as $3.52 \pm 0.01 \times 10^9 M_{\odot}$, the nonzero BH spin is $a_* = 0.32 \pm 0.04$, and the accretion rate is $\dot m=0.274 \pm 0.001$. The velocities of the detected absorbers lie in the range of 6330-108135 km/s. When we consider that absorption is caused by the CIV ion, one absorber is folding toward the nucleus with a velocity of 73887 km/s. We derived a BI index of about 20300 km/s and a mass outflow rate up to 38.5 % of the source accretion rate. The high absorption observed in SDSS J110511.15+530806.5 is evidence of fast winds that place the source in the group of objects on the border with UFO (ultra-fast outflows), strong broad absorption line (BAL), and fast failed radiatively accelerated dusty outflow (FRADO). This absorption affects the BH mass measurement by two orders of magnitude as compared to virial mass estimation.
