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: Statistics of Substructure Discovered within the Scattering Disk on RadioAstron Baselines of up to 235,000 km
C. R. Gwinn, M. V. Popov, N. Bartel +15
We discovered fine-scale structure within the scattering disk of PSR B0329+54 in observations with the RadioAstron ground-space radio interferometer. Here, we describe this phenome…
RadioAstron Studies of the Nearby, Turbulent Interstellar Plasma With the Longest Space-Ground Interferometer Baseline
T. V. Smirnova, V. I. Shishov, M. V. Popov +14
RadioAstron space-ground VLBI observations of the pulsar B0950+08, conducted with the 10-m space radio telescope in conjunction with the Arecibo 300-m telescope and Westerbork Synt…
