The Automatic Learning for the Rapid Classification of Events (ALeRCE) project

The ALeRCE broker is a Chilean-led broker which is processing the alert stream from the Zwicky Transient Facility (ZTF) and which aims to become a Community Broker for the Vera C. Rubin Observatory and its Legacy Survey of Space and Time (LSST), as well as other large etendue survey telescopes. We are using Cloud Infrastructure and Machine Learning models to bring real-time processed products and services to the astronomical community.

ALeRCE is funded by the Millennium Institute for Astrophysics – MAS, the Center for Mathematical Modeling - CMM at Universidad de Chile, and since 2020 the Data Observatory, in collaboration with researchers from Universidad Adolfo Ibáñez - UAI, Universidad Austral de Chile - UACH (Informatics), Universidad Católica de Chile - UC (Astronomy), Universidad de Chile - UCH (Astronomy - DAS, Electrical Engineering - DIE), Universidad de Concepción - UdeC (Informatics), Universidad Nacional Andres Bello – UNAB (Astronomy), Universidad de Santiago de Chile - USACH (Statistics), Universidad Tecnológica Metropolitana - UTEM (Computer Science), Universidad de Valparaíso - UV (Astronomy), and REUNA in Chile, and international researchers from Caltech and Harvard U. and U. of Washington.
