Cosmography Course
This course equips you with hands-on skills to master cosmography using real astronomical survey data. You will learn to clean catalogs, convert redshifts to distances with solid cosmological models, map large-scale structures like clusters, filaments, and voids in 2D and 3D, and handle uncertainties, biases, and errors effectively. Perfect for physics experts seeking reliable cosmic mapping tools and precise distance estimates from upcoming surveys.

What will I learn?
Gain practical expertise in cosmography: select sky areas, clean and process survey catalogs, correct for extinction, apply quality filters, create 2D/3D maps, estimate distances from redshifts using cosmological principles, identify clusters, filaments, voids, and manage errors, biases with reproducible methods for future data.
