What will I learn?
The Cosmography Course gives you practical skills to map large-scale structure using real survey data. Learn to select sky regions, retrieve and clean catalogs, handle extinction, and apply quality cuts. Build 2D and 3D visualizations, estimate distances from redshift with robust cosmological assumptions, detect clusters, filaments, and voids, and manage uncertainties, biases, and future survey improvements with reproducible tools.
Elevify advantages
Develop skills
- Map large-scale structure: detect clusters, filaments, and voids from survey data.
- Convert redshifts to distances: apply cosmological models with reproducible scripts.
- Clean and merge sky catalogs: apply cuts, flags, cross-matching, and extinction fixes.
- Build 2D and 3D cosmography maps: use HEALPix, matplotlib, and interactive tools.
- Quantify biases and errors: correct for selection effects, cosmic variance, and noise.

Your classes are perfect. I got the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... thank you for everything you do, I've already recommended you to others...
