Reconstructing Video from Interferometric Measurements of Time-Varying Sources
Katherine L. Bouman, Michael D. Johnson, Adrian V. Dalca +4
Very long baseline interferometry (VLBI) makes it possible to recover images of astronomical sources with extremely high angular resolution. Most recently, the Event Horizon Telesc…
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…
Computational Imaging for VLBI Image Reconstruction
Katherine L. Bouman, Michael D. Johnson, Daniel Zoran +3
Very long baseline interferometry (VLBI) is a technique for imaging celestial radio emissions by simultaneously observing a source from telescopes distributed across Earth. The cha…
Imaging an Event Horizon: Mitigation of Scattering Toward Sagittarius A*
Vincent L. Fish, Michael D. Johnson, Ru-Sen Lu +10
The image of the emission surrounding the black hole in the center of the Milky Way is predicted to exhibit the imprint of general relativistic (GR) effects, including the existenc…
