论文摘要
随着快速无线电爆发（FRB）的定位到类似于银河系的星系，并发现从SGR J1935+2154的明亮无线电爆发，其能量与外层次无线电爆发相当，因此很明显。通过研究FRB的环境，在银河系中未观察到的磁性形成机制的证据可能变得显而易见。在本文中，我们使用FRB宿主星系样本和完整的核心折叠超新星（CCSN）宿主样本来确定FRB祖细胞是否与CCSNE出生的磁铁群相一致。我们还将FRB宿主与氢贫血超新星（SLSNE-I）和长伽马射线爆发（LGRB）进行了比较，以确定FRB宿主的群体是否与可能连接到毫秒磁铁的瞬态群体兼容。在使用一种新颖的方法来扩展每个宿主星系的恒星质量和恒星形成速率以$ z = 0 $星系的统计代表之后，我们发现CCSN宿主和FRB与来自相同分布的产生一致。此外，FRB宿主分布与SLSNE-I和LGRB宿主的分布不一致。在当前的FRB宿主星系样品中，我们的分析表明，FRB与通过巨型，高磁性星的倒塌而出生的磁铁群一致。
With the localization of fast radio bursts (FRBs) to galaxies similar to the Milky Way and the detection of a bright radio burst from SGR J1935+2154 with energy comparable to extragalactic radio bursts, a magnetar origin for FRBs is evident. By studying the environments of FRBs, evidence for magnetar formation mechanisms not observed in the Milky Way may become apparent. In this paper, we use a sample of FRB host galaxies and a complete sample of core-collapse supernova (CCSN) hosts to determine whether FRB progenitors are consistent with a population of magnetars born in CCSNe. We also compare the FRB hosts to the hosts of hydrogen-poor superluminous supernovae (SLSNe-I) and long gamma-ray bursts (LGRBs) to determine whether the population of FRB hosts is compatible with a population of transients that may be connected to millisecond magnetars. After using a novel approach to scale the stellar masses and star-formation rates of each host galaxy to be statistically representative of $z=0$ galaxies, we find that the CCSN hosts and FRBs are consistent with arising from the same distribution. Furthermore, the FRB host distribution is inconsistent with the distribution of SLSNe-I and LGRB hosts. With the current sample of FRB host galaxies, our analysis shows that FRBs are consistent with a population of magnetars born through the collapse of giant, highly magnetic stars.
