- A reconstruction of the Event Horizon Telescope (EHT) image of the M87 black hole from the 2017 data set
https://iopscience.iop.org/article/10.3847/2041-8213/acc32d
From the abstract, "We present a new reconstruction of the Event Horizon Telescope (EHT) image of the M87 black hole from the 2017 data set. We use PRIMO, a novel dictionary-learning-based algorithm that uses high-fidelity simulations of accreting black holes as a training set. By learning the correlations between the different regions of the space of interferometric data, this approach allows us to recover high-fidelity images even in the presence of sparse coverage and reach the nominal resolution of the EHT array."
