Diffractive interstellar scintillation of the quasar J1819+3845 at 21 cm*

We report the discovery of fast, frequency-dependent intensity variations from the scintillating intra-day variable quasar J1819+3845 at 21 cm which resemble diffractive interstellar scintillations observed in pulsars. The observations were taken with the Westerbork Synthesis Radio Telescope on a do...
