Title: 由潮汐力矩对齐的中等大小黑洞喷流是否触发了3C 279伽马射线耀斑？

Abstract: The shorter-than-Schwarzschild 3C 279 variability flare on June 2015 is very puzzling. Its nature cannot be due to any NS merging nor to a medium sized (hundred million solar mass) BH collapse. Our preliminary model is based on the long-life (a third of a year) merging of a medium size BH (hundred of solar mass) jet spiralling toward the largest AGN one, (billion solar mass), that is dragging by tidal torques the medium small size BH jet along the main AGN 3C 279 one. The tidal torque is aligning both jets toward Earth. The twin overlapping blazars may offer at once a long and a short scale variability consistent with the surprising Fermi discovers.

Abstract: 2015年6月观测到的比史瓦西半径短的3C 279 变幅暴发现象令人困惑。 它的性质不可能是由任何中子星合并引起，也不是由某种中等质量（数千万太阳质量）黑洞塌缩造成。 我们初步的模型基于这样一个过程：一个中等质量黑洞（数百个太阳质量）喷流以螺旋形式向更大的活动星系核（数十亿太阳质量）靠近并合并，这一过程持续了大约四分之一年，同时由潮汐力拖动较小的中等质量黑洞喷流沿着主要的活动星系核3C 279喷流运动。 潮汐力使这两个喷流都朝向地球方向对齐。 这对重叠的耀变星可能同时提供长周期和短周期的变化，这与费米卫星的惊人发现一致。
