The Jeremiah Horrocks Institute (JHI) is pleased to announce that we will be hosting the first joint Oxford and Lancashire Colloquium in the (northern) spring of 2026: Cosmological Features on the Largest Scales: Theory and Observations. This meeting will bring together theoretical and observational cosmologists to discuss cosmological large-scale structure (LSS) on the largest scales, i.e., at and beyond the BAO scale. Discussion topics will include: large-scale structure, structure-formation theory, cosmological models, observational anomalies, and consistency with simulations.
