Open Call to the Inaugural Lorentz Center Workshop

We are inviting participants to join a focused Lorentz Center workshop on building the scientific and technical basis for AI-accelerated astrophysical discovery.

The consortium has two goals: to design how future astrophysicists and cosmologists will do science in collaboration with AI, and to build a joint-representation foundation model that understands heterogeneous physical data. The model should support embeddings for serendipity and retrieval, generative inference across linked observations and simulations, and agentic scientific workflows guided by human judgement.

The week will stay deliberately narrow. Monday will define shared vocabulary, flagship use cases, and evaluation targets. The rest of the week will focus on the joint-representation model: the relevancy graph, tokenisation implications, long-context architecture, training protocol, MVP scope, funding, and post-workshop roadmap.

Who should join

We are especially interested in contributors who bring:

• concrete astrophysical or cosmological discovery workflows;
• expertise in multimodal data, simulations, instruments, archives, or provenance;
• experience with representation learning, generative models, long-context systems, agentic AI, uncertainty, or evaluation;
• interest in open-source infrastructure, governance, funding, and sustained collaboration.

Expected outputs

By Friday we aim to leave with:

• selected use cases with explicit evaluation targets;
• a Relevancy Graph v0 for the required data relationships;
• an Architecture and Training Protocol v0 for the model;
• an MVP backlog, hackathon artifacts, and named owners;
• a consortium roadmap for funding, governance, and follow-up work.
