AI总结:

研究通过多信使观测排除原始黑洞作为KM3-230213A事件起源的可能性,基于时间依赖的观测视野和缺乏预爆信号。

摘要:

黑洞预计通过霍金辐射结束其寿命,发射所有标准模型粒子在极高能级。附近原始黑洞(PBH)的蒸发被提出解释KM3NeT报告的高能中微子事件。此类场景要求源极近地球,暗示可探测伽马射线和宇宙射线发射。考虑伽马射线观测站的时间依赖视野,发现当前实验应已观测到预爆信号,而中微子望远镜也会在爆发前检测到低能事件。此类多信使信号的缺失强烈反对在最小4DSchwarzschild场景中原始黑洞作为KM3-230213A事件的起源。

英文摘要:

Black holes are expected to end their lifetime in a burst of Hawking radiation, emitting all Standard Model particles at ultra-high energies. The evaporation of a nearby primordial black hole (PBH) has been proposed as an explanation for the high-energy neutrino-like event reported by KM3NeT. Such a scenario requires the source to be extremely close to Earth, implying detectable gamma-ray and cosmic-ray emission. Accounting for the time-dependent field of view of gamma-ray observatories, we find that current experiments should have observed a pre-burst signal, while neutrino telescopes would also detect lower-energy events before the burst. The absence of such multimessenger signals strongly disfavors a PBH origin of the KM3-230213A event in the minimal 4D Schwarzschild scenario.
