AMPEL is a modular and scalable platform with explicit provenance tracking, suited for systematically processing large and heterogeneous datasets either in real time or offline. This includes selecting, analysing, updating, combining, enriching and reacting to data. It is unique in simultaneously providing access to realtime astronomical data streams, hosting reproducible science pipelines and interface to astronomical archives. Currently supported research spans various areas of time-domain astrophysics, including multi-messenger projects involving neutrinos and/or gravitational waves as well as supernova science.
AMPEL provides users direct access to complete, high throughput realtime astronomical data streams from ZTF. User groups have members from 10+ European countries divided into channels focusing on infant supernovae, cosmology, lensed supernovae, Tidal Disruption Events and optical counterparts to multimessenger transients.
Users of AMPEL are assumed to be organised into working groups, each maintaining a channel. A channel constitutes both a scientific pipeline, the processing of real-time data streams through it and the real-time reaction/conclusion. Support offered under this proposal: Support will be given both in the design stage, where AMPEL developers will assist in code development as well as hosting a test environment. The latter will include an offline test mode with a static set of alerts. Support will also exist in terms of keeping the real-time AMPEL unit live and operational.
