Observations of Intrahour Variable Quasars: Scattering in our Galactic Neighbourhood
H. E. Bignall, D. L. Jauncey, J. E. J. Lovell +3
Interstellar scintillation (ISS) has been established as the cause of the random variations seen at centimetre wavelengths in many compact radio sources on timescales of a day or l…
Properties of the Scattering Screen in Front of Scintillating Quasar PKS 1257-326
H. E. Bignall, D. L. Jauncey, J. E. J. Lovell +3
PKS 1257-326 is a quasar showing extremely unusual, rapid interstellar scintillation (ISS), which has persisted for at least a decade. Simultaneous observations with the VLA and AT…
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…
