Rapid interstellar scintillation of PKS 1257-326: Two-station pattern time delays and constraints on scattering and microarcsecond source structure

Rapid interstellar scintillation of PKS 1257-326: Two-station pattern time delays and constraints on scattering and microarcsecond source structure

We report measurements of time delays of up to 8 minutes in the centimeter-wavelength variability patterns of the intrahour scintillating quasar PKS 1257326, as observed between the VLA and the ATCA on three separate epochs. These time delays confirm interstellar scintillation as the mechanism respo...
