Double Compton and Cyclo-Synchrotron in Super-Eddington Disks, Magnetized Coronae, and Jets
Jonathan C. McKinney, Jens Chluba, Maciek Wielgus +2
We present an extension to the general relativistic radiation magnetohydrodynamic code HARMRAD to account for emission and absorption by thermal cyclo-synchrotron, double Compton,…
The Optics of Refractive Substructure
Michael D. Johnson, Ramesh Narayan
Newly recognized effects of refractive scattering in the ionized interstellar medium have broad implications for very long baseline interferometry (VLBI) at extreme angular resolut…
High Resolution Linear Polarimetric Imaging for the Event Horizon Telescope
Andrew A. Chael, Michael D. Johnson, Ramesh Narayan +3
Images of the linear polarization of synchrotron radiation around Active Galactic Nuclei (AGN) identify their projected magnetic field lines and provide key data for understanding…
Extreme Brightness Temperatures and Refractive Substructure in 3C273 with RadioAstron
Michael D. Johnson, Yuri Y. Kovalev, Carl R. Gwinn +8
Earth-space interferometry with RadioAstron provides the highest direct angular resolution ever achieved in astronomy at any wavelength. RadioAstron detections of the classic quasa…
