论文摘要
最近，包括Swift-Bat，GBM和Lhaaso在内的几个望远镜观察到了毫无用处和最高的长期伽马射线，来自伽马射线爆发命名为Grb221009a，grb221009a命名为Grb221009a（$ z = 0.151 $ $ z = 0.151 $），在2022年10月9日，我们的传统距离都遭受了较高的距离。 地球。我们提出，存在一个sub-mev至$ o（10）$ meV重中微子，并具有过渡性磁性偶极矩，通过该偶极偶矩中微子在GRB处产生重中微子。然后，它很长一段距离到我们的银河系，并腐烂到中微子和一个光子。以这种方式，在GRB生产的原始高能光子可以在长途衰减中生存。
Recently, several telescopes, including Swift-BAT, GBM, and LHAASO, have observed the ever highest-energy and long-duration gamma-rays from a gamma-ray burst named as GRB221009A (located at a red-shift of $z=0.151$) on October 9, 2022. Conventional understanding tells us that very high-energy photons produced at such a far distance suffer severe attenuation before reaching the Earth. We propose the existence of a sub-MeV to $O(10)$ MeV heavy neutrino with a transitional magnetic dipole moment, via which the heavy neutrino is produced at the GRB. It then travels a long distance to our galaxy and decays into a neutrino and a photon, which is observed. In such a way, the original high-energy photon produced at the GRB can survive long-distance attenuation.
