We describe the process to design, architect, and implement a transformative enhancement of the Event Horizon Telescope (ngEHT). This program - the next-generation Event Horizon Telescope (ngEHT) - will form a networked global array of radio dishes capable of making high-fidelity real-time movies of supermassive black holes (SMBH) and their emanating jets. This builds upon the EHT principally by deploying additional modest-diameter dishes to optimized geographic locations to enhance the current global mm/submm wavelength Very Long Baseline Interferometric (VLBI) array, which has, to date, utilized mostly pre-existing radio telescopes. The ngEHT program further focuses on observing at three frequencies simultaneously for increased sensitivity and Fourier spatial frequency coverage. Here, the concept, science goals, design considerations, station siting and instrument prototyping are discussed, and a preliminary reference array to be implemented in phases is described.

  1. GRMHD accretion beyond the black hole paradigm: Light from within the shadow

    astro-ph.HE 2026-04 accept novelty 7.0 of 10

    3D GRMHD simulations of accretion onto a JMN-1 horizonless singularity produce a magnetically arrested disk with an accretion rate of ~3e-6 Eddington matching M87* observations and EHT-consistent images, plus central ...

  2. Dark matter environments and safeguards for spacetime inference from horizon scale interferometry

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Using public 2017 M87* closure data, a frozen Kerr source fails an absolute adequacy test and the differential tidal-charge response fails numerical convergence, so no posterior or bound is reported.

  3. $\tt BlackHawk$ $\tt v3.0$: Hawking Radiation from Regular Black Holes

    gr-qc 2026-06 unverdicted novelty 5.0 of 10

    BlackHawk v3.0 adds Hawking temperatures and greybody factors for multiple regular black hole metrics to an existing public code via numerical routines.

  4. Active Galactic Nuclei as high-energy neutrino sources

    astro-ph.HE 2026-06 accept novelty 2.5 of 10

    AGN (jetted and non-jetted) are viable high-energy neutrino sources, with TXS 0506+056 and NGC 1068 as the only statistically significant associations so far, while gamma-ray blazars contribute only a small fraction o...

  5. Active Galactic Nuclei as high-energy neutrino sources

    astro-ph.HE 2026-06 unverdicted novelty 2.0 of 10

    Review summarizing correlations between astrophysical neutrinos and gamma-ray/radio AGN, specific source associations, proposed production mechanisms, and future prospects.
