AI 中文摘要
基于合成偏振观测，我们通过同步辐射偏振强度（SPI）和同步辐射偏振梯度（SPG）定性研究了磁化星际介质（ISM）的间歇性。我们的分析得出三个主要发现：（1）磁化ISM的间歇性受到磁化和可压缩性的强烈调制，显著的调制效应主要出现在强磁化和高可压缩性的区域。（2）在随机磁场占主导的条件下，磁化ISM的特征间歇性依赖于电子谱指数。（3）在强法拉第退极化情况下，SPG能够识别更精细的三维分形结构。SPI和SPG的协同应用显著提高了从实际观测中探测磁化ISM间歇性的可靠性。
英文摘要
Based on synthetic polarization observations, we qualitatively investigate the intermittency of the magnetized interstellar medium (ISM) through synchrotron polarization intensity (SPI) and synchrotron polarization gradient (SPG). Three principal findings emerge from our analysis: (1) The intermittency of the magnetized ISM is strongly modulated by magnetization and compressibility, with pronounced modulation effects predominantly observed in regimes characterized by strong magnetization and high compressibility. (2) The characterized intermittency of the magnetized ISM demonstrates a dependence on the electron spectral index under conditions where the random magnetic field dominates. (3) SPG enables the identification of finer three-dimensional fractal structures in the case of strong Faraday depolarization. The synergistic application of SPI and SPG substantially enhances the reliability of probing magnetized ISM intermittency from real observations.
