SCiMMA developers led a collaboration with the SNEWS project, an international network of neutrino detectors designed to discover the next galactic supernova. SCiMMA and developers collaboratively developed the SNEWS 2.0 app, which extends the
hop-client to receive and process alerts from SNEWS's internal data streams hosted on
A summary and demonstration of the collaboration software is availabe on YouTube
The collaboration is detailed in publication available on arXiv written by members from both SCiMMA and SNEWS, and is currently under peer-review (as of March 2022)
SCiMMA members are involved with the AMON group at the Pennsylvania State University, which began integrating
hop-client into its existing MMA alert processing system. A summary presentation about the integration is available online
