The JetCurry Code. I. Reconstructing Three-Dimensional Jet Geometry from Two-Dimensional images
摘要：
本文提出了一种基于马尔可夫链蒙特卡罗（MCMC）和有限记忆Broyden-Fletcher-Goldfarb-Shanno（BFGS）优化算法的射流几何模型重建方法。我们的目标是使用观测数据来模拟活动星系核喷流的三维几何形状，而观测数据本质上是二维的。许多活动星系核喷流在千秒差距尺度上显示出复杂的热点和弯曲。在喷流框架中这些弯曲的结构可能与我们在天空框架中看到的完全不同，这是由我们特定的观察几何学改变的。本征结构的知识将有助于理解的外观的磁场，从而发射和粒子加速过程中的长度的射流。我们提出了所使用的方法，以及一个案例研究的基础上，该地区的M87喷气。
英文摘要：
We present a reconstruction of jet geometry models using numerical methods based on a Markov ChainMonte Carlo (MCMC) and limited memory Broyden-Fletcher-Goldfarb-Shanno (BFGS) optimized algorithm. Our aim is to model the three-dimensional geometry of an AGN jet using observations, which are inherently two-dimensional. Many AGN jets display complex hotspots and bends over the kiloparsec scales. The structure of these bends in the jets frame may be quite different than what we see in the sky frame, transformed by our particular viewing geometry. The knowledge of the intrinsic structure will be helpful in understanding the appearance of the magnetic field and hence emission and particle acceleration processes over the length of the jet. We present the method used, as well as a case study based on a region of the M87 jet.
