The Micro-Arcsecond Scintillation-Induced Variability (MASIV) Survey II: The First Four Epochs
J. E. J. Lovell, B. J. Rickett, J-P. Macquart +8
We report on the variability of 443 flat spectrum, compact radio sources monitored using the VLA for 3 days in 4 epochs at ~ 4 month intervals at 5 GHz as part of the Micro-Arcseco…
The Origin of Radio Scintillation In the Local Interstellar Medium
Jeffrey L. Linsky, Barney J. Rickett, Seth Redfield
We study three quasar radio sources (B1257-326, B1519-273, and J1819+385) that show large amplitude intraday and annual scintillation variability produced by the Earth's motion rel…
Modeling of Interstellar Scintillation Arcs from Pulsar B1133+16
Frank S. Trang, Barney J. Rickett
The parabolic arc phenomenon visible in the Fourier analysis of the scintillation spectra of pulsars provides a new method of investigating the small scale structure in the ionized…
MASIV:The Microarcsecond Scintillation-Induced Variability Survey
J. E. J. Lovell, D. L. Jauncey, C. Senkbeil +8
We are undertaking a large-scale 5 GHz VLA survey of the northern sky to search for rapid intra-day variability (IDV). Over four observing epochs we found that 56% of the sources s…
International Colloquium "Scattering and Scintillation in Radio Astronomy" was held on June 19-23, 2006 in Pushchino, Moscow region, Russia
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…
Interstellar Scintillation Observations of 146 Extragalactic Radio Sources
B. Rickett, T. J. W. Lazio, F. D. Ghigo
From 1979--1996 the Green Bank Interferometer was used by the Naval Research Laboratory to monitor the flux density from 146 compact radio sources at frequencies near 2 and 8 GHz.…
