Cosmography Course
Gain mastery in cosmography through practical exercises with astronomical survey data. Learn redshift-to-distance conversions, mapping of large-scale structures like clusters, filaments, and voids, plus managing uncertainties. Perfect for physicists seeking reliable 2D and 3D cosmic maps and precise distance measurements using robust, reproducible methods.

What will I learn?
This course equips you with hands-on skills to map the universe's large-scale structure using real astronomical survey data. You'll select sky regions, retrieve and process catalogues, correct for extinction, apply quality filters, create 2D and 3D visualisations, estimate distances from redshifts with solid cosmological models, identify clusters, filaments, and voids, and handle uncertainties, biases, and enhancements for future surveys with reproducible tools.
