The Scattering and Intrinsic Structure of Sagittarius A* at Radio Wavelengths
Michael D. Johnson, Ramesh Narayan, Dimitrios Psaltis +12
Radio images of the Galactic Center supermassive black hole, Sagittarius A* (Sgr A*), are dominated by interstellar scattering. Previous studies of Sgr A* have adopted an anisotrop…
Reversals in the Direction of Polarization Rotation in OJ 287
M. H. Cohen, H. D. Aller, M. F. Aller +7
We have obtained a smooth time series for the Electric Vector Position Angle (EVPA) of the blazar OJ 287 at centimeter wavelengths, by making adjustments to archival value…
The extreme blazar AO 0235+164 as seen by extensive ground and space radio observations
A. M. Kutkin, I. N. Pashchenko, M. M. Lisakov +10
Clues to the physical conditions in radio cores of blazars come from measurements of brightness temperatures as well as effects produced by intrinsic opacity. We study the properti…
