摘要
利用 Planck 卫星在 9 个频段的全天巡天数据，搜索了所有 274 个已知银河系超新星遗迹的辐射。其中，16 个遗迹在至少两个 Planck 频段中被探测到。 compiling 了从射电到微波的谱能量分布，以确定微波辐射的发射机制。仅在 IC 443 一例中，高频辐射明确来自与超新星遗迹相关的尘埃。在所有情况下，低频辐射均源自同步辐射。对于许多源（包括蟹状星云和 PKS 1209-51/52），明显的单一幂律分布符合相对论性粒子群的能量分布连续延伸至高能区的预测。在几个源中观测到流量密度相对于射电辐射外推值的下降。它们的谱能量分布可近似为折线幂律 ，其谱指数 alpha 在 10-60 GHz 范围内的转折频率以上增加了 0.5-1。该转折可能归因于同步辐射损耗。
