Toward a realistic test of black-hole movie correlations as a probe of extreme lensing
Barbora Bezděková, Shahar Hadar
In an optically thin setting, gravitational lensing around a black hole creates multiple delayed images of any localized source, appearing at different positions on the observer's…
The Black Hole Explorer: Motivation and Vision
Michael D. Johnson, Kazunori Akiyama, Rebecca Baturin +65
We present the Black Hole Explorer (BHEX), a mission that will produce the sharpest images in the history of astronomy by extending submillimeter Very-Long-Baseline Interferometry…
Universal Interferometric Signatures of a Black Hole's Photon Ring
Michael D. Johnson, Alexandru Lupsasca, Andrew Strominger +14
The Event Horizon Telescope image of the supermassive black hole in the galaxy M87 is dominated by a bright, unresolved ring. General relativity predicts that embedded within this…
