A new generation of large etendue survey telescopes such as the Zwicky Transient Facility (ZTF) and the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) are producing large streams of alerts which are being ingested, annotated and classified by a new generation of astronomical alert brokers such as ALeRCE, AMPEL, ANTARES, Babamul, Fink, Lasair, Pitt-Google, Point of Interest, or SNAPS.
In order to enable new science with these alert streams, brokers are developing a new layer in the time domain ecosystem, experimenting with new ways of enriching and filtering this data. A diversity of solutions are being tested, but there is a need for more interaction between brokers, their community of users, and the alert generation teams. Thus, two broker teams, ALeRCE and Fink, in collaboration with other alert broker teams, the Vera C. Rubin Observatory, and its Science Collaborations (SCs), put together a proposal for the LSSTC Enabling Science Program 2020, whose logistics component was awarded by the LSST Corporation with the following objectives:
- Presentation of envisioned products and services by broker teams.
- Presentation of detailed scientific cases by the SCs and a discussion on how brokers can most effectively help them reach their goals.
- Proposal of possible community standards, benchmarks, or initiatives to achieve more interoperability and resilience.
- Creation of a high quality repository with the contents of the workshops, including talks and hands-on material.
The event is the first part of two workshops. This first workshop will establish baselines about the LSST project and alert stream status; basic requirements of the SCs and expected outcomes; and the status of proposed brokers, their interfaces and current science modules. The second workshop will be 4-6 months after this first workshop to assemble the developments triggered by the first workshop and reflections from the different users and collaborations.
The first workshop is planned for Oct 27-28th, 2020. You can explore the topics of discussion on the first two days of this workshop below.
