Horizon-scale variability of M87* from 2017--2021 EHT observations
The Event Horizon Telescope Collaboration
We report three epochs of polarized images of M87* at 230\,GHz using data from the Event Horizon Telescope (EHT) taken in 2017, 2018, and 2021. The baseline coverage of the 2021 ob…
Selective Dynamical Imaging of Interferometric Data
Joseph Farah, Peter Galison, Kazunori Akiyama +16
Recent developments in very long baseline interferometry (VLBI) have made it possible for the Event Horizon Telescope (EHT) to resolve the innermost accretion flows of the largest…
First Sagittarius A* Event Horizon Telescope Results. II. EHT and Multi-wavelength Observations, Data Processing, and Calibration
The Event Horizon Telescope Collaboration
We present Event Horizon Telescope (EHT) 1.3 mm measurements of the radio source located at the position of the supermassive black hole Sagittarius A* (Sgr A*), collected during th…
Prospects for ray-tracing light intensity and polarization in models of accreting compact objects using a GPU
Monika Moscibrodzka, Aristomenis Yfantis
The Event Horizon Telescope (EHT) has recently released high-resolution images of accretion flows onto two supermassive black holes. Our physical understanding of these images depe…
The Event Horizon Telescope Image of the Quasar NRAO 530
Svetlana Jorstad, Maciek Wielgus, Rocco Lico +27
We report on the observations of the quasar NRAO 530 with the Event Horizon Telescope (EHT) on 2017 April 5-7, when NRAO 530 was used as a calibrator for the EHT observations of Sa…
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…
