论文摘要
我们已经收集了一个新的深{\ it chandra x射线天文台}（{\ it cxo}）PSR B2224+65和“吉他星云”的暴露，绘制复杂的X射线结构。这伴随着新的{\ it hst} h $α$的吉他头图像。比较{\ it Hst}和{\ it CXO}在25年内的4个时期内结构，我们限制了点亮细丝的TEV颗粒的演变。跨场扩散似乎是通过灯丝锋利的前缘后面的注入的颗粒增强的，解释了细丝宽度及其不断发展的表面亮度曲线。
We have collected a new deep {\it Chandra X-ray Observatory} ({\it CXO}) exposure of PSR B2224+65 and the `Guitar Nebula', mapping the complex X-ray structure. This is accompanied by a new {\it HST} H$α$ image of the head of the Guitar. Comparing the {\it HST} and {\it CXO} structures in 4 epochs over 25 years, we constrain the evolution of the TeV particles that light up the filament. Cross-field diffusion appears to be enhanced, likely by the injected particles, behind the filament's sharp leading edge, explaining the filament width and its evolving surface brightness profile.
