Green Bank Telescope observations of the water masers of NGC 3079: accretion disk magnetic field and maser scintillation
W. H. T. Vlemmings, H. E. Bignall, P. J. Diamond
We present observations of the 22 GHz water megamasers in the circumnuclear disk of NGC 3079 obtained with the Green Bank Telescope. The data are analyzed for circular polarization…

V. I. Shishov, W. A. Coles, B. J. Rickett +52
Topics of the Colloquium: a) Interplanetary scintillation b) Interstellar scintillation c) Modeling and physical origin of the interplanetary and the interstellar plasma turbulence…
Rapid interstellar scintillation of PKS B1257-326: two-station pattern time delays and constraints on scattering and microarcsecond source structure
H. E. Bignall, J. -P. Macquart, D. L. Jauncey +3
We report measurements of time delays of up to 8 minutes in the centimeter wavelength variability patterns of the intra-hour scintillating quasar PKS 1257-326 as observed between t…
Interstellar scintillation as a probe of microarcsecond scale structure in quasars
H. E. Bignall, D. L. Jauncey, J. E. J. Lovell +9
Observations over the last two decades have shown that a significant fraction of all flat-spectrum, extragalactic radio sources exhibit flux density variations on timescales of a d…
