The MASIV legacy: Surveying AGN intra-day variability at radio wavelengths

Koay, J. Y.; Macquart, J. P; Rickett, B. J.; Bignall, H. E.; Jauncey, David; Pursimo, T; Reynolds, C; Lovell, James E J; Kedziora-Chudczer, Lucyna L.; Ojha, R.


The Micro-arcsecond Scintillation-Induced Variability (MASIV) Survey and its follow-up observations have provided large datasets of AGN intra-day variability (IDV) at radio wavelengths. These data have shown that IDV arises mainly from scintillation caused by scattering in the ionized interstellar medium (ISM) of our Galaxy, based on correlation with Galactic latitudes and line-of-sight Galactic electron column densities. The sensitivity of interstellar scintillation (ISS) towards source...[Show more]
