Invitation to Apply: Rubin-Euclid Derived Data Products Implementation Working Group

The Euclid Consortium and the Rubin Project are seeking individuals to serve on an implementation working group (IWG) that will define a roadmap to develop the jointly derived data products (DDP) based on the combination of Euclid and Rubin observations. DDPs constructed from the combination of Rubin and Euclid data have the potential to open up new discovery space beyond that of what each mission can achieve independently.

The creation of the IWG follows from a comprehensive effort that engaged the Euclid and Rubin communities to define the DDPs needed. The report produced by this effort, which includes recommendations and an extensive specification of the DPPs to be developed, is published in (Guy, Cuillandre, et al., 2022). The formation of the joint Euclid/Rubin IWG represents the next step needed to produce the DDPs, and to respond to the cross-project recommendations presented in the report.

Euclid and Rubin leadership have identified the two co-leads, Drs. James Colbert (Euclid) and Tod Lauer (Rubin), who will lead the DDP Implementation Working Group. The co-leads are seeking experts in the relevant technical areas to make recommendations for “who”, “where”, “how” and “with what funding” the jointly derived data products (DDP) shall be created and served to the Rubin and Euclid communities and establish a prioritization and roadmap to the production of the 63 DDPs defined in the aforementioned report.

The group shall:

• Establish a roadmap for the creation of the 63 DDPs recommended in the Guy, Cuillandre et al. report, including prioritization and timelines for each DDP, explicitly identifying which DDPs can and should be created immediately (i.e. without significant new resources).

• Identify what technical capabilities individuals need to have to develop the 63 DDPs and, where possible, identify candidates with those capabilities and skills.

• Identify infrastructure requirements for the creation of the DDPs.

• Identify which bodies and organizations might financially support the creation of the DDPs and develop cases to obtain that support.

• Deliver a roadmap to the Rubin and Euclid leadership and continue to update Rubin and Euclid leadership on a quarterly basis on its progress.

We seek applicants with a wide range of skill sets. Areas of expertise that we need include the funding of scientific projects, the development of infrastructure and services for the processing, access, and analysis of peta-scale datasets, and the creation of algorithms and pipelines for the processing of astronomical data. The majority of the DDPs will be scientifically targeted photometric catalogs, so knowledge of the issues and pitfalls surrounding the combination of datasets with different spatial resolutions will also be valuable. The DDPs cover a wide scientific range, from tracking solar system objects to identifying drop-out primaeval galaxies. The IWG will not be able to include experts on every applicable astronomical subject, but some effort will be made to seek applicants with different scientific backgrounds, particularly for areas wiIth unique and pressing needs, such as the follow-up of transient sources.

The IWG will be limited to roughly a dozen members (equally split between people who identify with Rubin and Euclid communities), so we are seeking motivated people with a strong interest in joint survey processing and the resultant derived data products who can invest the significant time needed to realize the goals of this project on the defined timescale. We anticipate a commitment of 1-2 years, with meetings every two weeks. We especially encourage applications for traditionally underrepresented groups. Individuals interested in joining the IWG are strongly encouraged to review the requirements and DPPs discussed in the Guy et al. white paper. Please feel free to reach out to either James Colbert ( or Tod Lauer ( if you have additional questions about the IWG or your application.

This application will be open through October 1, 2023.
