论文摘要
我们使用长波长阵列的两个站点报告了潜在宇宙无线电瞬态源的检测。该瞬态于2017年10月18日检测到了天体赤道附近的UTC，同时减少了LWA1和LWA-SV站的10,240小时的档案全套图像。在34 MHz处检测到的瞬态持续时间为15-20秒，LWA1时的磁通密度为842 +/- 116 JY，在LWA-SV时为830 +/- 92 JY。瞬态源尚未重复，其性质尚未得到充分理解。 Pan-Stars光学望远镜已检测到同一天瞬态位置误差圆边缘发生的超新星。
We report the detection of a potential cosmic radio transient source using the two stations of the Long Wavelength Array. The transient was detected on 18 October 2017 08:47 UTC near the celestial equator while reducing 10,240 hours of archival all-sky images from the LWA1 and LWA-SV stations. The detected transient at 34 MHz has a duration of 15 - 20 seconds and a flux density of 842 +/- 116 Jy at LWA1 and 830 +/- 92 Jy at LWA-SV. The transient source has not repeated, and its nature is not well understood. The Pan-STARRS optical telescope has detected a supernova that occurred on the edge of the position error circle of the transient on the same day.
