摘要
我们报告了使用 MeerKAT 射电望远镜对一次性快速射电暴（FRB）20190714A 以及两个重复 FRB 20190711A 和 20171019A 的持久射电辐射的搜寻。对于 FRB 20171019A，我们还使用高能立体望远镜系统（H.E.S.S.）在甚高能伽马射线波段进行了同步观测，并搜寻了紫外、光学和 X 射线波段的信号。对于该 FRB，我们得到紫外流量上限为 1.39x10^-16 erg/cm^-2/s/Amstrong，X 射线上限约为 6.6x10^-14 erg/cm^-2/s，以及甚高能伽马射线流量（Phi）（E > 120 GeV）< 1.7 x 10^-12 erg/cm^-2/s。我们在 FRB 20190711A 和 20171019A 的位置处得到持久辐射的射电上限约为 15 microJy/beam，但探测到与 z = 0.2365 处的 FRB 20190714A 相关的弥散射电辐射，其峰值亮度约为 53 microJy/beam。这代表首次探测到可能与 FRB 20190714A 寄主（星系）相关的射电连续谱辐射，也是已知第三个具有此类关联的 FRB。鉴于可能与一个微弱持久源相关，FRB 20190714A 可能是一个重复 FRB，其年龄介于 FRB 20121102A 与 FRB 20180916A 之间。对这些 FRB 重复暴的并行搜寻未发现新探测，对于 1 ms 持续时间的暴，流量下限为 0.08 Jy ms。
