Green bank telescope observations of the water masers of NGC 3079: Accretion disk magnetic field and maser scintillation

We present observations of the 22 GHz H2O megamasers in the circumnuclear disk of NGC 3079 obtained with the Green Bank Telescope. The data are analyzed for circular polarization due to the Zeeman-induced splitting of the H2O maser lines. No circular polarization is detected, and we derive a 1 upper...
