论文摘要
宇宙中磁场的起源是一个空旷的问题。可能在早期生产的种子磁场可能已经在今天的原始形式附近幸存下来，为原始宇宙提供了一个未开发的窗口。最新观察到来自Blazar TXS 0506+056的高能量中微子与电磁对应物相关的广泛波长，可用于通过Neutrinos和Gamma射线之间的时间延迟以及胶质闪光液体的时间依赖性探测乳层间磁场。使用广泛的三维蒙特卡洛模拟，我们提出了一种限制这些领域的新方法。我们将其应用于TXS 0506+056，并首次考虑到磁场强度及其连贯性长度的约束，考虑到每个磁场的六个数量级。
The origin of magnetic fields in the universe is an open problem. Seed magnetic fields possibly produced in early times may have survived up to the present day close to their original form, providing an untapped window to the primeval universe. The recent observations of high-energy neutrinos from the blazar TXS 0506+056 in association with an electromagnetic counterpart in a broad range of wavelengths can be used to probe intergalactic magnetic fields via the time delay between the neutrinos and gamma rays as well as the time dependence of the gamma-ray fluxes. Using extensive three-dimensional Monte Carlo simulations, we present a novel method to constrain these fields. We apply it to TXS 0506+056 and, for the first time, derive constraints on both the magnetic-field strength and its coherence length, considering six orders of magnitude for each.
