论文摘要

我们报告了费米卫星检测到的伽马射线爆发(GRB)的快速后续观察结果,以寻找相关的快速无线电爆发。观察结果是用澳大利亚平方公里阵列探路者以1.2-1.4 GHz的频率进行的。一组20次爆发,其中4次是短的GRB,随后是典型的潜伏期约一分钟,在爆发后长达11个小时的时间内。使用4096分散测量试验搜索数据,最大分散度度量为3763 PC CM $^{ - 3} $,对于脉冲宽度$ W $,在1.256至40.48 ms的范围内。对于20个GRB中的任何一个中的任何一个,未观察到关联的脉冲无线电排放在$ 26 {\ rm jy ms}(w/1 {\ rm ms})$中。

We report the results of the rapid follow-up observations of gamma-ray bursts (GRBs) detected by the Fermi satellite to search for associated fast radio bursts. The observations were conducted with the Australian Square Kilometre Array Pathfinder at frequencies from 1.2-1.4 GHz. A set of 20 bursts, of which four were short GRBs, were followed up with a typical latency of about one minute, for a duration of up to 11 hours after the burst. The data was searched using 4096 dispersion measure trials up to a maximum dispersion measure of 3763 pc cm$^{-3}$, and for pulse widths $w$ over a range of duration from 1.256 to 40.48 ms. No associated pulsed radio emission was observed above $26 {\rm Jy ms} (w/1 {\rm ms})^{-1/2}$ for any of the 20 GRBs.
