Processing System for Coherent Dedispersion of Pulsar Radio Emission
Girin I. A., Likhachev S. F., Andrianov A. S. +5
The work describes a system for converting VLBI observation data using the algorithms of coherent dedispersion and compensation of two-bit signal sampling. Coherent dedispersion is…
Technical constraints on interstellar interferometry and spatially resolving the pulsar magnetosphere
M. V. Popov, N. Bartel, A. S. Andrianov +6
Scintillation of pulsar radio signals caused by the interstellar medium can in principle be used for interstellar interferometry. Changes of the dynamic spectra as a function of pu…
Electron density variations in the interstellar medium and the average frequency profile of a scintle from pulsar scintillation spectra
N. Bartel, M. S. Burgin, E. N. Fadeev +4
We observed the scintillation pattern of nine bright pulsars at 324 MHz and three at 1.68 GHz and analyzed the wavenumber spectrum which is related to electron density variations o…
Ionospheric effects in VLBI measured with space-ground interferometer RadioAstron
M. V. Popov, N. Bartel, M. S. Burgin +2
We report on slow phase variations of the response of the space-ground radio interferometer RadioAstron during observations of pulsar B0329+54. The phase variations are due to the…
Substructure of visibility functions from scattered radio emission of pulsars through space VLBI
M. V. Popov, N. Bartel, M. S. Burgin +3
We report on the substructure of visibility functions in the delay domain of PSRs B0329+54, B0823+26, B0834+06, B1933+16 and B0833-45 (Vela) observed with earth-earth and RadioAstr…
PSR B0329+54: Substructure in the scatter-broadened image discovered with RadioAstron on baselines up to 330,000 km
M. V. Popov, N. Bartel, C. R. Gwinn +13
We have resolved the scatter-broadened image of PSR B0329+54 and detected substructure within it. These results are not influenced by any extended structure of a source but instead…
