论文摘要
快速无线电爆发（FRB）191001位于高度恒星星系的螺旋臂上，观察到的色散度量（DM）为507 PC CM $^{ - 3} $。从总DM中减去播层间介质和我们的银河系的贡献，一个人的贡献可能超过200 pc cm $^{ - 3} $，这可能是由FRB的主机Galaxy贡献的。在这项工作中发现，FRB 191001的位置与其父型星系螺旋臂中超新星（SNE）的分布一致。如果此事件确实是由于SN爆炸造成的，那么，从对多余DM的SN贡献的分析来看，核心折叠（CC）通道比热核失控优选。对于CC爆炸，取决于周围介质的密度，为无线电爆发提供动力的中央发动机的年龄在几年至几十年之内。但是，观察到的FRB 191001的旋转度量并未确认无线电爆发已经通过了年轻SN的残余。
Fast radio burst (FRB) 191001 is localised at the spiral arm of a highly star-forming galaxy with an observed dispersion measure (DM) of 507 pc cm$^{-3}$. Subtracting the contributions of the intergalactic medium and our Milky Way Galaxy from the total DM, one gets an excess of around 200 pc cm$^{-3}$, which may have been contributed by the host galaxy of the FRB. It is found in this work that the position of FRB 191001 is consistent with the distribution of supernovae (SNe) in the spiral arm of their parent galaxies. If this event is indeed due to an SN explosion, then, from the analysis of the SN contributions to the excess DM, a core-collapse (CC) channel is preferred over a thermonuclear runaway. For the CC explosion, depending on the density of the surrounding medium, the age of the central engine that powers the radio burst is within a couple of years to a few decades. However, the observed rotation measure of FRB 191001 does not confirm the fact that the radio burst has passed through the remnant of a young SN.
