乌鲁木齐天文站脉冲星观测研究新进展

THE RECENT PROGRESS OF PULSAR OBSERVATION AT NAO OF CHINA

乌鲁木齐天文站自 1 999年研制完成 1 .5GHz频段室温双偏振消色散接收系统。 2 0 0 2年又完成 1 .5GHz频段致冷式双偏振消色散接收系统。我们成功地完成了第一个国际合作协议的任务。为在我国建立高灵敏度的观测脉冲星设备和取得优秀的脉冲星观测结果作出了贡献。为了进一步发展乌站脉冲星观测 ,第二个合作协议包括利用致冷式系统进行脉冲星大样本的监测和建立低频段的基带技术的消色散系统。

The 1.5GHz de-dispersion pulsar-timing observation system of UAO has been made since 1999. A cryogenic receiver for 18cm observations was constructed since 2002. We have successfully accomplished the missions proposed in International Agreement 1. The good results under Agreement 1 have contributed greatly to the development of observing facilities with high sensibility of pulsar work, and have given good observational results. The second Agreement for future development of the pulsar observation at UAO, included that the observations of a large sample of pulsars using the 18cm cryogenic receiver and construction of a low-frequency pulsar observing system using the base-band technique.
