论文摘要
快速无线电爆发（FRB）是源自造影距离的无线电发射的毫秒脉冲。每次爆发的无线电分散都通过大多位于播层间介质中的血浆中的介入来赋予。我们在红移$ z = 1.016 \ pm 0.002 $的形态复杂的宿主星系系统中观察到了一个爆发，frb 20220610a。爆发的红移和分散与通过大量层间培养基的大量材料一列一致。爆发显示通过其他湍流磁化等离子体的证据，可能与宿主星系有关。我们使用$ 2 \ times 10^{42} $ erg的爆发能量来修改FRB的最大能量。
Fast radio bursts (FRBs) are millisecond-duration pulses of radio emission originating from extragalactic distances. Radio dispersion on each burst is imparted by intervening plasma mostly located in the intergalactic medium. We observe a burst, FRB 20220610A, in a morphologically complex host galaxy system at redshift $z=1.016 \pm 0.002$. The burst redshift and dispersion are consistent with passage through a substantial column of material from the intergalactic medium. The burst shows evidence for passage through additional turbulent magnetized plasma, potentially associated with the host galaxy. We use the burst energy of $2 \times 10^{42}$ erg, to revise the maximum energy of an FRB.
