The AMPEL System as an Official VRO Community Broker: Current Developments and Applications

AMPEL is a modular and scalable platform with explicit provenance tracking, suited for systematically processing large — possibly complex and heterogeneous — datasets either in real time or offline. This includes selecting, analyzing, updating, combining, enriching and reacting to data. It was originally developed as a candidate to process alert stream data from the Vera Rubin Observatory (VRO), and made use of data from the Zwicky Transient Facility as an intermediate step to reach that goal. Recently, the VRO committee selected AMPEL to be one of its official community brokers; the only one which was integrally developed in Germany. The AMPEL system is currently operating in its 0.74 release version. In this talk we present some of the features of this release, and also the forthcoming 0.8 version. We will also present the most recent results of the applications that integrate Machine Learning models into its infrastructure for detection and classification of transients.
