摘要:

我们目前的红外观测3C 58与斯皮策太空望远镜和加拿大-法国-夏威夷望远镜。使用IRAC相机,我们对整个源进行了成像,从而清晰地检测到了3.6和4.5微米的星云。导出的通量值与X射线光谱外推到红外波段是一致的,表明同步加速器光谱中的任何冷却中断必须发生在软X射线波段附近。我们还探测到PSR J 0205 +6449周围的环面,PSR J 0205 +6449是为3C 58提供动力的65 ms脉冲星。环面光谱需要在红外和X射线波段之间有一个中断,也许是多个中断。这个复杂的光谱是注入星云的粒子的印记,对3C 58宽带光谱的演化有相当大的影响。我们说明了这些影响,并讨论了脉冲星风星云的宽带光谱的建模这些意见的影响。

英文摘要:

We present infrared observations of 3C 58 with the Spitzer Space Telescope and the Canada-France-Hawaii Telescope. Using the IRAC camera, we have imaged the entire source resulting in clear detections of the nebula at 3.6 and 4.5 microns. The derived flux values are consistent with extrapolation of the X-ray spectrum to the infrared band, demonstrating that any cooling break in the synchrotron spectrum must occur near the soft X-ray band. We also detect the torus surrounding PSR J0205+6449, the 65 ms pulsar that powers 3C 58. The torus spectrum requires a break between the infrared and X-ray bands, and perhaps multiple breaks. This complex spectrum, which is an imprint of the particles injected into the nebula, has considerable consequences for the evolution of the broadband spectrum of 3C 58. We illustrate these effects and discuss the impact of these observations on the modeling of broadband spectra of pulsar wind nebulae.
