摘要

本文对超新星遗迹W44 (SNR) 70 GHz以下的综合连续无线电频谱进行了分析，测试了导致其特殊形状的不同发射模型。普朗克太空望远镜的观测使得分析来自信噪比的无线电发射的高频部分成为可能。虽然无线电连续谱的质量(同一频率上数据点的高度分散)使我们无法作出明确的结论，但强调了对这一残余进行旋转尘埃发射探测的可能性。此外，由于同步加速器损耗而产生的凹进特征，不能通过目前对该信噪比的集成无线电连续谱的了解来确定地排除。[南斯拉夫]塞族共和国部长项目;176005:发射星云:结构与演化]

On the Integrated Continuum Radio Spectrum of Supernova Remnant W44 (G34.7-0.4): New Insights From Planck

In this paper, the integrated continuum radio spectrum of supernova remnant (SNR) W44 was analyzed up to 70 GHz, testing the different emission models that can be responsible for its particular shape. The observations by the Planck space telescope made it possible to analyze the high frequency part of radio emission from SNRs. Although the quality of radio continuum spectrum (a high scatter of data points at same frequencies) prevents us to make definite conclusions, the possibility of spinning dust emission detection towards this remnant is emphasized. In addition, a concave-down feature, due to synchrotron losses, can not be definitely dismissed by the present knowledge of the integrated radio continuum spectrum of this SNR.
