Emergence and disappearance of microarcsecond structure in the scintillating quasar J1819+3845
The 4.8-GHz light curves of the scintillating intraday variable quasar J1819+3845 during 2004-2005 exhibit sharp structure, down to a time-scale of 15 min, that was absent from lightcurves taken prior to this period and from the 2006 light curves. Analysis of the light curve powerspectra show that t...
