摘要:

几乎所有的快速无线电RRAT型瞬变都是具有罕见脉冲的脉冲星,以前都使用分米波长检测到。我们在这里提出了34个瞬态检测米波长在我们的日常监测在赤纬-9o < decl。<+42o。25个瞬变是新的RRAT。根据我们的早期观察,我们确认检测到7例RRAT。34个瞬变现象中的一个被确定为新的脉冲星J1326+3346。与此同时,在分米波长检测到的35个RRAT中,包括在研究区域,只有一个是由美国J1848+1518检测到的。从单脉冲到达时间开始,找到了6个RRAT的周期。四分之三的RRAT被观察到一次以上,研究地区的RRAT总数翻了一番。

英文摘要:

Nearly all fast radio RRAT-type transients that are pulsars with rare pulses have been previously detected using decimetre wavelengths. We present here 34 transients detected at metre wavelengths in our daily monitoring at declinations -9o < decl. < +42o. 25 transients are new RRATs. We confirmed the detection of 7 RRATs based on our early observations. One of the 34 detected transients was determined to be a new pulsar J1326+3346. At the same time, out of 35 RRATs detected at the decimetre wavelengths and included in the studied area, only one was detected by us J1848+1518. The periods of 6 RRATs were found from the time of arrival of single pulses. Three quarters of all RRATs were observed more than once and the total number of RRATs in the area studied has doubled.
