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 connected wedge theorem and its consequences
Alex May, Jonathan Sorce, Beni Yoshida
In the AdS/CFT correspondence, bulk causal structure has consequences for boundary entanglement. In quantum information science, causal structures can be replaced by distributed en…
X-ray view of a merging supermassive black hole binary candidate SDSSJ1430+2303: Results from the first ~200 days of observations
Liming Dou, Ning Jiang, Tinggui Wang +7
Recently we discovered an unprecedented supermassive black hole binary (SMBHB) candidate in the nearby Seyfert galaxy SDSS J1430+2303, which is predicted to merge within three year…
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…
