论文摘要
我们使用光谱能分布(SED)模型研究了脉冲星风星云(PWN)3C 58的宽带发射特性。我们尝试同时匹配PWN中X射线发射的宽带SED和空间变化。我们进一步解释了一个可能的FAR-IR功能,该功能最近在3C 58中提出了一个提示:$ \ sim $$ $$ 10^{11} $ ghz的小bump在Planck和Herschel乐队中。虽然外部灰尘发射可能很容易解释观察到的凸起,但可能是来源的内部发射,暗示着额外的颗粒群体。尽管对凸起的意义不高,但在这里我们使用发射模型探索了IR颠簸的可能起源,并发现具有GEV能量的电子种群可以解释凸起。如果它是在PWN中产生的,则可能会提供有关粒子加速度和流动中流动的新见解。
We investigate broadband emission properties of the pulsar wind nebula (PWN) 3C 58 using a spectral energy distribution (SED) model. We attempt to match simultaneously the broadband SED and spatial variations of X-ray emission in the PWN. We further the model to explain a possible far-IR feature of which a hint is recently suggested in 3C 58: a small bump at $\sim$$10^{11}$ GHz in the PLANCK and Herschel band. While external dust emission may easily explain the observed bump, it may be internal emission of the source implying an additional population of particles. Although significance for the bump is not high, here we explore possible origins of the IR bump using the emission model and find that a population of electrons with GeV energies can explain the bump. If it is produced in the PWN, it may provide new insights into particle acceleration and flows in PWNe.
