Magnetohydrodynamic Simulations of the Supernova Remnant G1.9+0.3
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 magnetohydrodynamical s...

| description | 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 magnetohydrodynamical 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 a density gradient and an environment with clump, which provides a possible explanation of the observation. |
