摘要
Abstract
Since the building up of Urumqi 25m radio telescope in 1993, except improving the VLBI system, we have developed the single dish astrophysics observational systems. Among them, the pulsar timing system was built at 18cm, which has been operational since mid-1999 with a receiver working in room temperature. Dedispersing is provided by a 2×128×2.5MHz filterbank based on PC data acquisition. Monitoring of pulse profile and intensity on 92cm to some pulsars are in progress. We obtained the spectrum of PSR B0329+54 by multi-frequency observations. Acoustic surface wave spectrometer and frequency synthesizer form the molecules spectrum observation system, have been developed at 1.3cm frequency. H2O maser observations have found more than 10 possible sources.关键词
