摘要:

使用LPA LPI射电望远镜进行了5年的监测观测,在96个空间波束中进行了搜索,每天覆盖17,000平方度。发现了五个新的病毒。在求和的功率谱中选择候选者进入谱图。噪声发生器的使用允许对数据进行重新归一化,并对天空中各个方向的功率谱进行正确的求和。因此,与单独的观察期相比,灵敏度增加了20倍以上。对于在赤纬+30 ° <dec时脉冲持续时间大于100 ms的雷达。<+40 °时,它等于1.2 mJy和0.4 mJy进入/离开银河平面。

英文摘要:

The search of pulsars in monitoring observations being carried out for 5 years using LPA LPI radio telescope was done in 96 spatial beams covering daily 17,000 square degrees. Five new pulsars were detected. Candidates into pulsars were selected in the summed power spectra. The use of a noise generator allowed to renormalize the data and to perform correct summing up of the power spectra for individual directions in the sky. Herewith, the sensitivity increased more than 20 times in comparison with individual sessions of observations. For pulsars with pulse durations greater than 100 ms at declinations +30o<dec.<+40o it is equal to 1.2 mJy and 0.4 mJy in/out of the Galaxy plane.
