- 适合天体物理研究者，助力理解星际介质中的复杂动力学。
我们提出一种基于计算机视觉的方法，用于在由超新星驱动的磁流体动力学模拟中精确实现三维超气泡的分割与追踪。借助先进的3D Transformer模型，该方法有效捕捉了这些天体结构的复杂形态及其动态演化过程。为验证技术效果，我们聚焦于一个由连续超新星爆炸驱动、并与周围介质发生显著相互作用的超气泡案例。模型成功生成了详细的3D分割掩码，使我们能够可视化并分析气泡结构随时间的演变。结果揭示了超气泡的生长模式、能量保留机制及其与周围星际物质的相互作用特征。这一跨学科方法不仅深化了对超气泡动力学的理解，还为研究宇宙中其他复杂现象提供了稳健的分析框架。
原文摘要 · Abstract (English)
We developed a computer vision-based methodology to achieve precise 3D segmentation and tracking of superbubbles within magnetohydrodynamic simulations of the supernova-driven interstellar medium. Leveraging advanced 3D transformer models, our approach effectively captures the complex morphology and dynamic evolution of these astrophysical structures. To demonstrate the technique, we specifically focused on a superbubble exhibiting interesting interactions with its surrounding medium, driven by a series of successive supernova explosions. Our model successfully generated detailed 3D segmentation masks, enabling us to visualize and analyze the bubble's structural evolution over time. The results reveal insights into the superbubble's growth patterns, energy retention, and interactions with surrounding interstellar matter. This interdisciplinary approach not only enhances our understanding of superbubble dynamics but also offers a robust framework for investigating other complex phenomena in the cosmos.
