Welcome to the next-generation Event Horizon Telescope Analysis Challenge!

The ngEHT project will add new capabilities and more stations to the existing Event Horizon Telescope.

These analysis challenges will help us understand the performance of different imaging algorithms on simulated data from the expanded array, and will help us assess how different array options might affect our ability to achieve our science goals.


The Challenge 1 and 2 results have been published in the ngEHT Special Issue of Galaxies. This paper can be used as a reference for the Analysis Challenges in general.

Schedule -- Challenge 4

In parallel to Challenge 4, we are also running the ngEHT Forecasting Tournament. Participation in this tournament is highly encouraged for everyone! See here for more information.
