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…
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…
Revealing compact structures of interstellar plasma in the Galaxy with RadioAstron
E. N. Fadeev, A. S. Andrianov, M. S. Burgin +6
The aim of our work was to study the spatial structure of inhomogeneities of interstellar plasma in the directions of five pulsars: B0823+26, B0834+06, B1237+25, B1929+10, and B201…
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…
Discovery of Substructure in the Scatter-Broadened Image of Sgr A*
C. R. Gwinn, Y. Y. Kovalev, M. D. Johnson +1
We have detected substructure within the smooth scattering disk of the celebrated Galactic Center radio source Sagittarius A* (SgrA*). We observed this structure at 1.3 cm waveleng…
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…
Multifrequency Study of Giant Radio Pulses from the Crab Pulsar with the K5 VLBI Recording Terminal
M. V. Popov, V. A. Soglasnov, V. I. Kondratiev +6
Simultaneous multifrequency observations of the Crab pulsar giant pulses (GPs) were performed with the 64-m Kalyazin radio telescope at four frequencies 0.6, 1.4, 2.2 and 8.3 GHz u…
