ngEHT: The next generation Event Horizon Telescope

Aims and scope

On April 10, 2019, after decades of effort by an international team, the Event Horizon Telescope (EHT) collaboration released the first images of a black hole. More recently, the EHT collaboration has published the first polarization images from the vicinity of the central black hole in M87, revealing the magnetism at the edge of the black hole event horizon. SgrA* is the other prime horizon-scale target for the EHT, and offers an ideal laboratory to perform further tests of gravity given its more accurate measurements of the black hole mass and distance, as compared with M87. The EHT collaboration will publish its first SgrA* results in Spring 2022, just before the EAS 2022 meeting.

The extraordinary success of the EHT brings an unprecedented historical opportunity to envision the next generation EHT (ngEHT), as the next-decade instrument capable of making the first real-time movies of supermassive black holes. With even sharper resolution, sensitivity, and much faster sampling of interferometric visibilities, the ngEHT will enable entirely new ways to study gravity, bringing into focus not only the persistent strong-field gravity features predicted by general relativity, but also the fine details of black hole accretion and relativistic jet launching that drive galaxy evolution and influence large scale structures in the Universe. Building upon the momentum of the first two ngEHT science meetings in Feb 2021 and Nov 2021, the 2022 EAS meeting in Valencia offers an unique opportunity for an in-person international meeting to further develop the key science cases and array design of the ngEHT.
