论文摘要
快速无线电爆发（FRB）的物理起源未知。已经建议用伽马射线爆发（GRB）出生的年轻磁铁是可能的中央发动机。我们通过系统地搜索来自110 FRB和1440 GRB的GRB-FRB空间关联来检验这样的假设。我们发现，Parkes望远镜发现的一个FRB事件，即171209，在空间上与历史悠久的长期GRB 110715a相吻合，$ z = 0.82 $。 GRB 110715a的余辉与由毫秒磁铁驱动的一致。 FRB 171209的外乳外分散度度量超过了伴随层间培养基的贡献，这可以解释为与GRB相关的年轻超新星残留物的贡献。总体而言，协会的重要性为$（2.28-2.55）σ$。如果确实是物理的，我们的结果表明，与长GRB相关的磁体可能至少是一些FRB的祖细胞。
The physical origin of fast radio bursts (FRBs) is unknown. Young magnetars born from gamma-ray bursts (GRBs) have been suggested to be a possible central engine of FRBs. We test such a hypothesis by systematically searching for GRB-FRB spatial associations from 110 FRBs and 1440 GRBs. We find that one FRB event, FRB 171209, discovered by the Parkes telescope is spatially coincident with a historical long-duration GRB 110715A at $z=0.82$. The afterglow of GRB 110715A is consistent with being powered by a millisecond magnetar. The extragalactic dispersion measure of FRB 171209 is in excess of that contributed by the intergalactic medium, which can be interpreted as being contributed by a young supernova remnant associated with the GRB. Overall, the significance of the association is $(2.28 - 2.55) σ$. If the association is indeed physical, our result suggests that the magnetars associated with long GRBs can be the progenitors of at least some FRBs.
