Demographics of black holes at 100 R scales: accretion flows, jets, and shadows
Dhanya G. Nair, Neil M. Nagar, Venkatessh Ramakrishnan +87
Using the Event Horizon Telescope (EHT), the gravitationally lensed rings around the supermassive black holes (SMBHs) in Messier 87 (M87) and Sagittarius A* (Sgr A*) have now been…
Machine- and deep-learning-driven angular momentum inference from BHEX observations of the photon ring
Joseph R. Farah, Jordy Davelaar, Daniel Palumbo +2
The photon ring is an important probe of black hole (BH) properties and will be resolved by the Black Hole Explorer (BHEX) for the first time. However, extraction of black ho…
First Very Long Baseline Interferometry Detections at 870μm
Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada +276
The first very long baseline interferometry (VLBI) detections at 870m wavelength (345GHz frequency) are reported, achieving the highest diffraction-limited angular resoluti…
The Black Hole Explorer: Using the Photon Ring to Visualize Spacetime Around the Black Hole
Peter Galison, Michael D. Johnson, Alexandru Lupsasca +2
The Black Hole Explorer (BHEX), an orbiting, multi-band, millimeter radio-telescope, in hybrid combination with millimeter terrestrial radio-telescopes, is designed to discover and…
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…
Prospects of Detecting a Jet in Sagittarius A* with VLBI
Erandi Chavez, Sara Issaoun, Michael D. Johnson +3
Event Horizon Telescope (EHT) images of the horizon-scale emission around the Galactic Center supermassive black hole Sagittarius A* (Sgr A*) favor accretion flow models with a jet…
