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.

  1. FRANZ: Framework for analytical one-zone blastwave dynamics

    astro-ph.GA 2026-07 accept novelty 6.0

    A local thin-shell blastwave framework recovers classical SNR limits and shows galactic shear, gravity, and filaments deform remnants and can systematically overestimate ages in structured media.
