What will I learn?
Gain hands-on skills in mapping cosmic large-scale structures using actual survey data. Master selecting sky areas, fetching and purifying catalogues, correcting for extinction, and using quality filters. Create 2D and 3D visual maps, calculate distances from redshift via solid cosmological models, spot clusters, filaments, voids, and tackle uncertainties, biases, plus prep for upcoming surveys with reliable tools.
