Brisken, Walter F., Macquart, Jean-Pierre, Gao, Jian-Jian, Rickett, Barney, Coles, William, Deller, Adam, ...
We have invented a novel technique to measure the radio image of a pulsar scattered by the interstellar plasma with 0.1 mas resolution. We extend the "secondary spectrum" analysis of parabolic arcs...
Interstellar Scintillation od Pulsar B0809+74 (1999)
Rickett, Barney, Coles, Bill, Markkanen, Jussi
Weak interstellar scintillations of pulsar B0809+74 were observed at two epochs using a 30m EISCAT antenna at 933 MHz. These have been used to constrain the spectrum, the distribution and the...
Radio Scintillation due to Discontinuities in the Interstellar Plasma Density (1999)
Lambert, Hendrik, Rickett, Barney
We develop the theory of interstellar scintillation as caused by an irregular plasma having a power-law spatial density spectrum with a spectral exponent of 4 corresponding to a medium with abrupt...
