论文摘要
进攻式射击场景已应用于解释在大约38年期间测得的Blazar 3C345中二十七个高亮体组件的VLBI-KINEMATIC。可以从双喷嘴系统中弹出超亮体结,形成双射流结构。两次喷嘴都可以以大约7.30元的周期和相同的方向前进。对于两个喷气式飞机,都可以存在稳定的预触及通用轨迹,沿着不同的结根据其根据其前进阶段移动。大多数结模型被模拟,以大约4至30的范围内加速其大量洛伦兹因子,并得出了其Lorentz/Doppler因子轮廓。结C9的无线电曲线与多普勒的增强曲线相吻合。双进攻喷嘴方案已应用于解释四个Blazars(3C279,OJ287,3C454.3和3C345)的VLBI-KINEMATIC。并进行了比较并进行了比较,并进行了比较,表明它们在物理合理的范围中,与一些与Black Black Black Hole Black Hole Binaries的理论参数一致。
The precessing jet-nozzle scenario has been applied to interpret the VLBI-kinematics of twenty-seven superluminal components in blazar 3C345 measured during an about 38-yr period. The superluminal knots could be ejected from a double jet-nozzle system forming a double-jet structure.Both nozzles could precess with a period of about 7.30yr and in the same direction.For both jets a steady precessing common trajectory could exist, along which different knots moved according to their precession phases. Most knots were model-simulated to be accelerated with their bulk Lorentz factor in the range of about 4 to 30 and their Lorentz/Doppler factor profiles were derived. The radio light-curves of knot C9 were well coincident with its Doppler boosting profile. The double precessing nozzle scenario has been applied to interpret the VLBI-kinematics for four blazars (3C279, OJ287, 3C454.3 and 3C345). The charateristic parameters of the four putative supermassive black hole binaries (including hole masses, orbital separation and gravitational radiation lifetime, etc.) were derived and compared, showing that they are in physically reasonable ranges, and well consistent with some theoretical arguments for close black hole binaries.
