Probing Accretion Turbulence in the Galactic Center with EHT Polarimetry
Chunchong Ni, Avery E. Broderick, Roman Gold
Magnetic fields grown by instabilities driven by differential rotation are believed to be essential to accretion onto black holes. These instabilities saturate in a turbulent state…
The Photon Ring in M87*
Avery E. Broderick, Dominic W. Pesce, Paul Tiede +48
We report measurements of the gravitationally lensed secondary image -- the first in an infinite series of so-called "photon rings" -- around the supermassive black hole M87* via s…
Hybrid Very Long Baseline Interferometry Imaging and Modeling with Themis
Avery E. Broderick, Dominic W. Pesce, Paul Tiede +2
Generating images from very long baseline interferometric observations poses a difficult, and generally not unique, inversion problem. This problem is simplified by the introductio…
Resolving the inner parsec of the blazar J1924-2914 with the Event Horizon Telescope
Sara Issaoun, Maciek Wielgus, Svetlana Jorstad +27
The blazar J1924-2914 is a primary Event Horizon Telescope (EHT) calibrator for the Galactic Center's black hole Sagittarius A*. Here we present the first total and linearly polari…
Millimeter light curves of Sagittarius A* observed during the 2017 Event Horizon Telescope campaign
Maciek Wielgus, Nicola Marchili, Ivan Marti-Vidal +28
The Event Horizon Telescope (EHT) observed the compact radio source, Sagittarius A* (Sgr A*), in the Galactic Center on 2017 April 5-11 in the 1.3 millimeter wavelength band. At th…
Horizonless spacetimes as seen by present and next-generation Event Horizon Telescope arrays
Astrid Eichhorn, Roman Gold, Aaron Held
We study the capabilities of present and future radio very-long-baseline-interferometry arrays to distinguish black holes from horizonless spacetimes. We consider an example of a h…
