AMPEL is a software framework for analysis of data streams. It was developed for multi-messenger astronomy and new, high-throughput, wide-field surveys like ZTF that require flexible tools for the selection and analysis of astrophysical transients. A key component is its modular design, where user-contributed software modules can be added to the platform in order to filter, analyze, update, rank, or react based on transient properties. The framework encourages provenance and keeps track of the varying information states that a transient displays. The latter concept includes information gathered over time, but also tracks varying data access levels and augmentations, e.g. improved calibration.
An AMPEL instance is currently operating at DESY, processing real-time alerts from optical, neutrino, and gravitational-wave telescopes. It is an open platform, where users can contribute both their own analysis units and channels that use them. AMPEL output can either be stored for offline analysis or used to trigger reactions in real time. The latter capability is used both for autonomous observations with robotic telescopes, submission of candidates to TNS, and transfer of data to different visualization frontends.
