AI 中文摘要
超新星遗迹（SNRs）是恒星反馈以及星际介质化学与动力学演化的关键示踪体。然而，在复杂天区中识别超新星遗迹仍具挑战性，尤其是仅能获取存档多波段数据时。我们旨在结合光学成像、射电连续谱数据及已有的SRG/eROSITA全天巡天X射线观测，搜寻圆规座内此前未被识别的超新星遗迹候选体，为后续确认提供优先级目标列表。候选遗迹依据联合诊断的强度分类。该联合分析对该区域已知遗迹的形态与光谱性质给出了更精准的约束，包括MSH 15-52和G320.6-1.6。此外，我们识别出一个新的有前景的超新星遗迹候选体G320.2-3.6。本研究是对圆规座区域超新星遗迹候选体的首次多波段搜寻。除G320.2-3.6外，还有三个天体（G319.8-2.0、G321.8-1.1和G320.5-1.8）成为后续射电、光谱光学观测及更深空间分辨X射线观测以确认其性质的有前景目标。
英文摘要
Supernova remnants (SNRs) are key tracers of stellar feedback and the chemical and dynamical evolution of the interstellar medium. However, identifying SNRs in complex regions remains challenging, particularly when only archival multi-wavelength data are available. We aim to search for previously unrecognized SNR candidates in the Circinus constellation by combining optical imaging, radio continuum data, and available SRG/eROSITA all-sky survey X-ray observations, to provide a prioritized list of targets for future confirmation. Candidate remnants were classified according to the strength of the combined diagnostics. This joint analysis yields improved constraints on the morphology and spectral properties of known remnants in the region, including MSH 15-52 and G320.6- 1.6. In addition, we identify a new promising SNR candidate, G320.2-3.6. Our study provides a first multi-wavelength search of SNR candidates in the Circinus region. In addition to G320.2-3.6, three objects (G319.8-2.0, G321.8-1.1, and G320.5-1.8) emerge as promising targets for follow-up radio, spectroscopic optical, and deeper, spatially resolved X-ray observations to confirm their nature.
