Session 57 - Interstellar Scattering and Scintillation as Tools in Radio Astronomy.
Display session, Wednesday, June 10
Atlas Ballroom,
We have carried out a survey of 126 flat-spectrum compact radio sources at 2.4, 4.8 and 8.6 GHz with the Compact Array of the Australia Telescope National Facility. Flux densities were measured with an accuracy of 0.5/that showed variations of 2/up to 2 days were noted. We find that the fraction of sources that show intra-day variations is roughly constant at 6/4.8 and 8.6 GHz. We show the sky distribution of the IDV sources and discuss the Survey results in terms of interstellar scattering as the cause of the variations.
