耀变体S5 0014+813：一个真实的或明显的怪物？
The blazar S5 0014+813: a real or apparent monster?
摘要：
耀变体发出的强硬X射线表明了一个非常强大的喷流的存在。如果喷流的能量反过来与质量吸积率有关，那么最明亮的硬X射线耀变体应该能够精确地确定最大的吸积率，从而确定最大的黑洞质量。这些想法被雨燕卫星对耀变体S5 0014+813的观测所证实，其红移z=3.366。斯威夫特用三种仪器探测到了这个来源，从光学到硬X射线。通过构造它的光谱能量分布，我们确信它的光-紫外发射是热的起源。把它与一个标准的光学厚的几何薄的吸积盘的辐射联系起来，我们发现一个质量为400亿太阳质量的黑洞，辐射量为爱丁顿值的40%。导出的质量是有史以来发现的最大的质量之一。超爱丁顿薄盘或厚盘与准直漏斗的存在，可以在原则上减少黑洞质量的估计，但往往产生光谱比观察到的更蓝。
英文摘要：
A strong hard X-ray luminosity from a blazar flags the presence of a very powerful jet. If the jet power is in turn related to the mass accretion rate, the most luminous hard X-ray blazars should pinpoint the largest accretion rates, and therefore the largest black hole masses. These ideas are confirmed by the Swift satellite observations of the blazar S5 0014+813, at the redshift z=3.366. Swift detected this source with all its three instruments, from the optical to the hard X-rays. Through the construction of its spectral energy distribution we are confident that its optical-UV emission is thermal in origin. Associating it to the emission of a standard optically thick geometrically thin accretion disk, we find a black hole mass of 40 billion solar masses, radiating at 40% the Eddington value. The derived mass is among the largest ever found. Super-Eddington slim disks or thick disks with the presence of a collimating funnel can in principle reduce the black hole mass estimate, but tends to produce spectra bluer than observed.
