论文摘要
北半球的调查以111 MHz的频率进行。在天空的每个点的总积累时间至少为一个小时。检测到75次脉搏发射来源。这些来源中有80%是在天线的侧叶中观察到的已知脉冲星。在十二个已知的脉冲星中检测到从一到几百个脉冲。对于四个脉冲星(J0157+6212,J1910+5655,J2337+6151,J2354+6155),最强的脉冲的狭窄和最强脉冲中峰值通量密度的比率是最强的脉冲,并且在平均曲线上表明它们可能是巨大的脉冲脉冲。检测到一个新的旋转无线电瞬变(RRAT)J0812+8626,具有分散度度量DM = 40.25 PC/cm3。
The survey of northern hemisphere were made at a frequency of 111 MHz. The total accumulation time at each point of the sky was at least one hour. 75 sources of pulse emission were detected. More then 80% of these sources are known pulsars observed in the side lobes of the antenna. From one to several hundreds pulses were detected in twelve known pulsars. For four pulsars (J0157+6212, J1910+5655, J2337+6151, J2354+6155) the narrowness of the strongest pulses and the ratio of peak flux densities in the strongest pulse and in the average profile indicate that they can be pulsars with giant pulses. One new rotating radio transient (RRAT) J0812+8626 with a dispersion measure DM=40.25 pc/cm3 was detected.
