Modeling Seven Years of Event Horizon Telescope Observations with Radiatively Inefficient Accretion Flow Models
Avery E. Broderick, Vincent L. Fish, Michael D. Johnson +6
An initial three-station version of the Event Horizon Telescope, a millimeter-wavelength very-long baseline interferometer, has observed Sagittarius A* (Sgr A*) repeatedly from 200…

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…
