Cosmography Course
This course equips you with hands-on skills to master cosmography using real survey data. You will learn redshift-to-distance conversions, mapping of large-scale structures like clusters, filaments, and voids, catalog cleaning, 2D/3D visualisations, and uncertainty management. Perfect for physics professionals seeking reliable cosmological tools and robust maps.
