英文摘要 | We present the status and results of pulsar observations at Urumqi Ob-servatory. Observations commenced with a pulsar timing system at the 25-m Urumqi Nanshan telescope in mid-1999; these were the first regular and high-quality pulsar observations in China. The center frequency of this system is 1540 MHz, and de-dispersion is provided by a 2£128£2:5 MHz filterbank/digitiser system. Observations over more than one year have resulted in updated positions and period parameters for 74 pulsars. Comparing with earlier observations we showed that long-term period and period-derivative fluctuations may be dominated by unseen glitches. Taking advantage of the available telescope time, we are also monitoring the variation of pulsar scintilla-tion dynamic spectra for a few strong pulsars. Scintillation parameters are measured and their variations are under study. We are planning to built a new system at a lower frequency so that frequency-dependent pulsar properties can be investigated. |
