Alert Brokers

A community alert broker, led from Chile, that ingests a survey's alert stream and classifies its transients and variable objects in real time with machine learning — first for the Zwicky Transient Facility and, in the era ahead, for Rubin.

NOIRLab's alert broker for time-domain astronomy, which filters and annotates survey alert streams to surface the events most worth following up. One of the community brokers selected to process the full Rubin alert stream.

A community alert broker built to process the alert streams of ZTF and Rubin, adding machine-learning classifications and value-added information so that astronomers can select the transients and variables they care about from millions of nightly alerts.

A UK-led community alert broker for the ZTF and Rubin alert streams, letting astronomers query, filter, and cross-match the live stream of changing objects on the sky.
