  This paper presents an interdisciplinary effort aiming to develop and share
sustainable knowledge necessary to analyze, understand, and use published
scientific results to advance reproducibility in multi-messenger astrophysics.
Specifically, we target the breakthrough work associated with the generation of
the first image of a black hole, called M87. The image was computed by the
Event Horizon Telescope Collaboration. Based on the artifacts made available by
EHT, we deliver documentation, code, and a computational environment to
reproduce the first image of a black hole. Our deliverables support new
discovery in multi-messenger astrophysics by providing all the necessary tools
for generalizing methods and findings from the EHT use case. Challenges
encountered during the reproducibility of EHT results are reported. The result
of our effort is an open-source, containerized software package that enables
the public to reproduce the first image of a black hole in the galaxy M87.
