论文摘要
在许多方面，在主动来源（例如Blazars）中产生的相对论喷气机是一个复杂的问题，其中大多数仍未完全理解。相对论喷射可能是由于物质和磁场的积聚在旋转黑洞上产生的。 Ergospher拖动效应在这些系统的极性方向上引发了以Poynting为主的流出。在附近的射电星系M87中，射流分辨率很高的观察结果以及其他几个物体的非热辐射的差异极快的证据表明，带电的颗粒会产生同步加速器发射，并且伽马射线非常接近射流的底部。如何将这些颗粒注入磁屏蔽流出是一个谜。在这里，我们探讨了在接近黑洞的热积聚流入中各种过程的影响，这可能导致中性颗粒的大量产生，这些颗粒通过喷气式漏斗中的歼灭和衰减，可能会在几个Schwarzsschild Radii的尺度上加载流出质量和带电的颗粒。
The generation of relativistic jets in active sources such as blazars is a complex problem with many aspects, most of them still not fully understood. Relativistic jets are likely produced by the accretion of matter and magnetic fields onto spinning black holes. Ergospheric dragging effects launch a Poynting-dominated outflow in the polar directions of these systems. Observations with very high resolution of the jet in the nearby radio galaxy M87 and evidence of extremely fast variability in the non-thermal radiation of several other objects indicate that charged particles produce synchrotron emission and gamma rays very close to the base of the jet. How these particles are injected into the magnetically shielded outflow is a mystery. Here we explore the effects of various processes in the hot accretion inflow close to the black hole that might result in the copious production of neutral particles which, through annihilation and decay in the jet's funnel, might load the outflow with mass and charged particles on scales of a few Schwarzschild radii.
