Abstract

The search for rotating radio transients (RRATs) was carried out at a frequency of 111 MHz, as daily observations carried out on the Large Phased Array (LPA) radio telescope at declinations of −9° < δ < +42°. Overall, 19 new RRATs were discovered for dispersion measures (DMs) from 2.5 to 72.6 pc cm−3. Estimates of the periods were obtained for three RRATs, with two of them (J0408+28; J0440+35) located at distances of 134 and 136 pc from Sun, placing them among the closest of all known RRATs.

从三年的监测数据中寻找旋转无线电瞬变体
对旋转射电瞬变体(RRATs)的搜索是在 111 MHz 频率下进行的,通过大型相控阵(LPA)射电望远镜在 -9° < δ +42° 的偏角范围内进行日常观测。总共发现了 19 个新的 RRAT,其色散度量(DMs)为 2.5 至 72.6 pc cm-3。其中两个(J0408+28;J0440+35)与太阳的距离分别为 134 和 136 pc,是所有已知 RRAT 中距离最近的。
