Transient processing and analysis using $\texttt{AMPEL}$: Alert Management, Photometry and Evaluation of Lightcurves

Understand

Both multi-messenger astronomy and new high-throughput wide-field surveys require flexible tools for the selection and analysis of astrophysical transients.

• We here introduce the Alert Management, Photometry and Evaluation of Lightcurves (AMPEL) system, an analysis framework designed for high-throughput surveys and suited for streamed data.
• AMPEL combines the functionality of an alert broker with a generic framework capable of hosting user-contributed code, that encourages provenance and keeps track of the varying information states that a transient displays.
• The latter concept includes information gathered over time and data policies such as access or calibration levels.
