Black Holes Inside and Out 2024: visions for the future of black hole physics

Niayesh Afshordi, Abhay Ashtekar, Enrico Barausse +27

The gravitational physics landscape is evolving rapidly, driven by our ability to study strong-field regions, in particular black holes. Black Holes Inside and Out gathered world e…

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 resolutio…

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…

The Black Hole Explorer: Photon Ring Science, Detection and Shape Measurement

Alexandru Lupsasca, Alejandro Cárdenas-Avendaño, Daniel C. M. Palumbo +6

General relativity predicts that black hole images ought to display a bright, thin (and as-of-yet-unresolved) ring. This "photon ring" is produced by photons that explore the stron…

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…

Bayesian Black Hole Photogrammetry

Dominic O. Chang, Michael D. Johnson, Paul Tiede +1

We propose a simple, analytic dual-cone accretion model for horizon scale images of the cores of Low-Luminosity Active Galactic Nuclei (LLAGN), including those observed by the Even…
