Abstract

During five years of daily observations, the search for new pulsars using the BSA LPI radio telescope in 96 spatial beams covering 17 000 square degrees was conducted. Five new pulsars were identified. Candidate pulsars were selected in summed power spectra. A noise generator was used to renormalize data and total the power spectra for individual directions correctly. As a result, the sensitivity increased by a factor of 10–20 relative to that in individual observational sessions. The sensitivity for pulsars with pulses longer than 100 ms at declinations +30° < δ < +40° was 1.2 and 0.4 mJy in and out of the galaxy plane, respectively.

使用BSA LPI射电望远镜检测五个新的脉冲星

摘要

在五年的每日观测中，使用BSA LPI射电望远镜在覆盖17000平方度的96个空间射束中进行了新脉冲星的搜索。确定了五个新的脉冲星。在总功率谱中选择了候选脉冲星。噪声发生器用于重新归一化数据并正确汇总各个方向的功率谱。结果，灵敏度相对于单个观察阶段提高了10-20倍。偏角为+ 30°<δ<+ 40°时脉冲大于100 ms的脉冲星的灵敏度分别为银河系平面内和银河系平面外的1.2和0.4 mJy。
