Reconstructing the Universe

This workshop will bring together researchers working at the intersection of theory, simulations, and observations to discuss new methods and challenges in extracting cosmological information from large-scale structure—particularly focusing on field-level inferences and reconstruction techniques for initial conditions and baryon acoustic oscillations. We aim to foster collaboration across survey boundaries and disciplines.

‍

Key topics include:

‍

• Reconstruction of the initial conditions and large-scale structure
• Synergies between galaxy clustering, weak lensing, and spectroscopic data
• Field-level inferences and simulation-based forward modeling
• Challenges in data analysis pipelines for upcoming surveys (e.g., LSST, Euclid, Roman, DESI, PFS)
