Abstract

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.

在普希诺多波束巡天中搜索旋转射电瞬变

摘要

我们已针对 116 个 RRAT 候选对象搜索了 111 MHz 的脉冲发射。在我们的搜索中，我们使用了子午线 128 光束大型相控阵射电望远镜获得的档案数据。每个候选人在八年的时间间隔内累积了大约六天的观察。检测到 11 个新的 RRAT。我们设法估计了其中 6 个的周期，并构建了 4 个 RRAT 的平均概况。一些候选者被证明是在射电望远镜旁瓣和干扰中观察到的已知脉冲星。对于一些候选者，我们未能找到任何信噪比大于七的脉冲，并且它们的性质仍然未知。
