Cross-Survey Cosmography: Precision Cosmology, Emerging Tensions and New Physics

Over the next decade, precision cosmology will be driven by a powerful synergy of large-scale surveys, including DESI, Euclid, Rubin–LSST, eROSITA, and Roman Space Telescope. While these surveys deliver unprecedented statistical precision, they are also revealing notable tensions in cosmological measurements, including discrepancies in the Hubble constant, late-time expansion history, and structure growth within ΛCDM.

Cross-Survey Cosmography: Precision Cosmology, Emerging Tensions, and New Physics will bring together experts across observational and theoretical domains to examine these challenges. By combining insights from BAO, supernovae, lensing, CMB, and time-delay cosmology, the meeting aims to distinguish systematics from genuine physical anomalies and assess whether current tensions point toward new physics or refined modeling within the standard framework.
