残余物内部的磁场增强
超新星遗迹(SNR)是恒星演化过程中产生的,被认为是产生高能粒子和宇宙射线的理想场所。SNR 中的磁场在确定发射粒子的能量方面起着关键作用。最近,Moeri Tao 及其同事利用射电和 X 射线辐射分析了超新星 SN 1006(包括东北壳和西南壳)的磁场,发现磁场强度局部增强了约 100 倍。MeerKAT射电望远镜的宽带射电数据(从1.37千兆赫到100千兆赫)不能用单一的幂律来描述,因为在36千兆赫左右的断裂频率处,光谱行为发生了明显的变化。出现这种特征的一个合理原因是电子冷却导致同步辐射损失。当电子冷却时间和 SNR 的动态时间尺度达到平衡时,就会出现这种冷却断裂。断裂频率与超过 2 mG 的磁场强度相对应。最小磁场强度为 10 μG,由电子和磁场能量密度的等分得到。

期刊介绍: Nature Astronomy, the oldest science, has played a significant role in the history of Nature. Throughout the years, pioneering discoveries such as the first quasar, exoplanet, and understanding of spiral nebulae have been reported in the journal. With the introduction of Nature Astronomy, the field now receives expanded coverage, welcoming research in astronomy, astrophysics, and planetary science. The primary objective is to encourage closer collaboration among researchers in these related areas. Similar to other journals under the Nature brand, Nature Astronomy boasts a devoted team of professional editors, ensuring fairness and rigorous peer-review processes. The journal maintains high standards in copy-editing and production, ensuring timely publication and editorial independence. In addition to original research, Nature Astronomy publishes a wide range of content, including Comments, Reviews, News and Views, Features, and Correspondence. This diverse collection covers various disciplines within astronomy and includes contributions from a diverse range of voices.
