| 摘 要： | 介绍上海天文台25 m射电望远镜首次单天线脉冲星观测。2010年4月23日,使用上海天文台位于佘山观测基地的25 m射电望远镜对脉冲星J0332+5434在L波段进行了观测,此次观测使用VLBI终端进行数据采集记录,通过对观测数据进行非相干消色散和周期折叠,成功获得目标源的平均轮廓。此次观测的成功,表明该天线具备开展单天线脉冲星观测的条件,并为上海天文台建设中的65 m天线的天文观测提供了参考,为将来自主研发脉冲星终端进行了技术储备。

| Abstract: | The first single-dish pulsar observation at the 25 m radio telescope of Shanghai astronomical observatory is presented.The observation was implemented in April 23,2010 in the L band,using the VLBI backend for data acquisition.And the source of the observation was pulsar J0332+5434. After applying the incoherent de-dispersion process to the data,the result is folded according to the period of the source.The average profile is obtained after the folding. Comparing the obtained average profile to the one relea... |
