利用超新星周边介质中的能量注入现象，通过观测前导黑体辐射来探测弱相互作用粒子，为暗物质研究提供了新的方法和约束。
摘要：
我们提出了一种新颖的策略，通过利用核心塌缩超新星（CCSNe）周围密集且受限的周边介质（CSM）来探测弱相互作用粒子（FIPs）。在原中子星中产生的FIPs可以在恒星爆发前通过衰变将大量可见能量注入到CSM中。这种能量注入会加热和电离CSM，建立由FIP诱导的光球，产生独特的前导黑体辐射。利用SN 2023ixf早期时间观测，我们将缺乏过度前导光度的观测转化为对MeV尺度暗光子等示例模型的严格新限制。我们的结果显著扩展了现有CCSN界限，并排除了之前未探索的参数空间区域。我们进一步证明，FIP诱导的尘埃亚limation为未来银河系超新星提供了稳健的诊断，开辟了探索暗部门的新途径。
英文摘要：
We propose a novel strategy to probe feebly interacting particles (FIPs) by exploiting the dense, confined circumstellar medium (CSM) surrounding core-collapse supernovae. FIPs produced in the protoneutron star can deposit substantial visible energy into the CSM via decay prior to the shock breakout from the progenitor star. This energy injection heats and ionizes the CSM, establishing an FIP-induced photosphere that generates distinctive precursor blackbody emission. Using early-time observations of supernova 2023ixf, we translate the nondetection of excessive precursor luminosity into stringent new constraints on MeV-scale dark photons as an exemplary model. Our results significantly extend existing core-collapse supernova bounds and exclude previously unexplored regions of parameter space. We further demonstrate that the FIP-induced dust sublimation offers key diagnostics for future Galactic supernovae, opening a new avenue to explore the dark sector.
