标题： Formation and Radiation Acceleration of Pair Plasmoids Near Galactic Black Holes

摘要： 我们定量研究了在银河系黑洞附近通过光子-光子碰撞产生的电子-正电子对等离子体团的形成和辐射加速。 终端喷射速度被发现完全由总吸积盘亮度、质子负载因子和吸积盘大小决定，与初始速度无关。 我们讨论了其在最近发现的银河系超光速源GRS1915、GROJ1655以及其他可能的银河系黑洞中的潜在应用。 显示英文摘要

摘要： We study quantitatively the formation and radiation acceleration of electron-positron pair plasmoids produced by photon-photon collisions near Galactic black holes (GBHs). The terminal ejecta velocity is found to be completely determined by the total disk luminosity, proton loading factor and disk size, with no dependence on the initial velocity. We discuss potential applications to the recently discovered Galactic superluminal sources GRS1915, GROJ1655 and possibly other GBHs.
