Long-term Scintillation Observations of Five Pulsars at 1540 MHz
From 2001 January to 2002 June, we monitored PSRs B0329+54, B0823+26, B1929+10, B2020+28 and B2021+51 using the Nanshan 25-m radio telescope of Urumqi Observatory to study their diffractive interstellar scintillation (DISS). The average interval between observations was about 9 days and the observation duration ranged between 2 and 6 hours depending on the pulsar. Wide variations in the DISS pa...
متن کاملThe Canadian geophysical long baseline interferometer
The Canadian geophysical long baseline interferometer, a new very long baseline interferometer system, has been developed and put into operation. The system tracks source delay and fringe rotation during observation using a wave front clock. After the low-noise receiver the signals from radio sources are channelized and down converted to baseband, each baseband channel is one bit digitized at a...
متن کامل2 Long Baseline Interferometric Observations of Cepheids
We present observations of the galactic cepheids η Aql and ζ Gem. Our observations are able to resolve the diameter changes associated with pulsation. This allows us to determine the distance to the Cepheids independent of photometric observations. We determine a distance to η Aql of 320 ± 32 pc, and a distance to ζ Gem of 362±38 pc. These observations allow us to calibrate surface brightness r...

متن کاملSINGLE-PULSE CHARACTERISTICS OF THE MILLISECOND RADIO PULSAR PSR B1937]21 AT 430 MHz
The single-pulse characteristics of the millisecond pulsar PSR B1937]21 are studied using the recently installed Caltech baseband recorder at the Arecibo Radio Observatory in Puerto Rico. This is the Ðrst such analysis of this object that includes both average intensity pulses as well as ““ giant pulses.ÏÏ Pulse ensemble-averaging techniques are developed in order to study the characteristics o...
