论文摘要
最年轻的银河系超新星残留G1.9+0.3在其无线电和X射线形态之间显示出离散的特征。观察到的无线电形态在北部具有最大的最大值，而X射线观察显示了东侧和西侧的两个“耳朵”。使用3D磁铁流体动力学模拟，我们研究了残留物的离散特征的形成。我们已经测试了不同的参数以更好地模拟，并在具有密度梯度和团块环境的环境下再现了类似的离散特征，从而提供了观察值的解释。
The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the north, while the X-ray observation shows two opposite 'ears' on the east and west sides. Using 3D magneto hydrodynamical simulations, we investigate the formation of the discrete feature of the remnant. We have tested different parameters for better simulation and reproduced similar discrete features under an environment with density gradient and an environment with clump, which provides a possible explanation of the observation.
