Observing---and Imaging---Active Galactic Nuclei with the Event Horizon Telescope
Vincent L. Fish, Kazunori Akiyama, Katherine L. Bouman +7
Originally developed to image the shadow region of the central black hole in Sagittarius A* and in the nearby galaxy M87, the Event Horizon Telescope (EHT) provides deep, very high…
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…
Radiative, two-temperature simulations of low luminosity black hole accretion flows in general relativity
A. Sadowski, M. Wielgus, R. Narayan +3
We present a numerical method which evolves a two-temperature, magnetized, radiative, accretion flow around a black hole, within the framework of general relativistic radiation mag…
Persistent Asymmetric Structure of Sagittarius A* on Event Horizon Scales
Vincent L. Fish, Michael D. Johnson, Sheperd S. Doeleman +69
The Galactic Center black hole Sagittarius A* (Sgr A*) is a prime observing target for the Event Horizon Telescope (EHT), which can resolve the 1.3 mm emission from this source on…
The Intrinsic Shape of Sagittarius A* at 3.5-mm Wavelength
Gisela N. Ortiz-León, Michael D. Johnson, Sheperd S. Doeleman +19
The radio emission from Sgr A is thought to be powered by accretion onto a supermassive black hole of at the Galactic Center. At millimete…
