Pitt-Google Broker

The Pitt-Google Broker is a cloud-based alert distribution service designed to provide near real-time processing of data from large-scale astronomical surveys like the Legacy Survey of Space and Time (LSST). LSST will deliver on order 10 million real-time alerts each night providing information on astronomical targets within 60 seconds of observation. The Pitt-Google Broker is a scalable broker system being designed to maximize the availability and usefulness of the LSST alert data by combining cloud-based analysis opportunities with value-added data products.

The Pitt-Google Broker runs on the Google Cloud Platform (GCP) and is currently focused on processing and serving alerts from the Zwicky Transient Facility (ZTF), and extending broker capabilities using ZTF, the LSST Alert Simulator, and the DECam Alliance for Transients (DECAT) stream.
