标题： Short-duration gamma-ray bursts from Kerr-Newman black hole mergers

摘要： 黑洞（BH）并合是引力波（GWs）的自然来源，并可能与电磁事件相关。 如果磁场在吸积过程中占主导地位，那么带有吸积盘的带电旋转黑洞所产生的事件可能会更加能量巨大且持续时间极短，因为强磁场周围的电离流体的吸引力通过回旋磁效应进一步增强了带电粒子的加速。 因此，更强的磁场和引力将为任何径向位移的流体提供向内的力，并使其以不断增加的速度朝旋转轴移动。 在旋转过程中的多次扭曲以及恢复性物质的存在下，这些事件可能产生一条沿着旋转轴以庞斯廷通量形式开始的狭窄强烈喷流，类似于Blandford-Znajek（BZ）机制。 我们研究了带电旋转黑洞，并获得了特征结果（例如，残余质量、磁场强度、光度、张开角、观测角以及观测角对SGRB光度探测的变化），这些结果与具有引力波关联的电磁对应物的罕见事件有很好的吻合。 这项研究为以强磁化盘主导能量提取过程的事件提供了新的见解。 显示英文摘要

摘要： Black hole (BH) mergers are natural sources of gravitational waves (GWs) and are possibly associated with electromagnetic events. Such events from a charged rotating BH with an accretion on to it could be more energetic and ultra-short-lived if the magnetic force dominates the accretion process because the attraction of ionized fluid with a strong magnetic field around the rotating BH further amplifies the acceleration of the charged particle via a gyromagnetic effect. Thus a stronger magnetic field and gravitational pull will provide an inward force to any fluid displaced in the radial direction and move it toward the axis of rotation with an increasing velocity. After many twists during rotation and the existence of restoring agents, Such events could produce a narrow intense jet starts in the form of Poynting flux along the axis of rotation resembling the Blandford-Znajek (BZ) mechanism. We investigated a charged rotating BH and obtained characteristic results (e.g., the remnant mass, magnetic field strength, luminosity, opening angle, viewing angle, and variation of viewing angle on the SGRB luminosity detection) that have a nice coincidence with rare events having GW associated with EM counterparts. This study gives a new insight into events with a strongly magnetized disk dominating the accretion process of energy extraction.
