摘要

摘要 我们搜索了116个RRAT候选天体的111 MHz脉冲发射。在搜索过程中,我们使用了子午线 128 波束大型相控阵射电望远镜获得的档案数据。我们为每个候选天体累积了大约六天的观测数据,时间间隔为八年。我们发现了 11 个新的 RRAT。我们成功地估算出了其中六个的周期,并为四个 RRAT 绘制了平均轮廓图。其中一些候选者是在射电望远镜侧叶和干扰中观测到的已知脉冲星。对于某些候选脉冲星,我们未能发现任何信噪比大于 7 的脉冲,因此它们的性质仍然未知。

Search for Rotating Radio Transients in the Pushchino Multibeam Survey

We have searched for pulse emission at 111 MHz toward 116 RRAT candidates. For our search we used the archival data obtained at the meridian 128-beam Large Phased Array radio telescope. About six days of observations in an interval of eight years were accumulated for each candidate. Eleven new RRATs were detected. We managed to estimate the periods for six of them and to construct the average profiles for four RRATs. Some of the candidates turned out to be known pulsars observed in the side lobes of the radio telescope and interference. For some of the candidates we failed to find any pulses with a signal-to-noise ratio greater than seven, and their nature remains unknown.
