Lyman-Alpha Story
Read the physics behind resonant scattering, then practice fitting line profiles to infer neutral hydrogen fractions.
Cosmology Guide
Learn Cosmology with Me
We will walk through the story of the universe step by step—blending simple explanations, practical exercises, and open data so you can build confidence at your own pace.
Focus Areas
These mini-modules keep things grounded: you learn a concept, see how we compute it, and explore what current surveys are revealing.
Weak Lensing Maps
Follow a gentle guide to shape measurements, convergence maps, and what they tell us about dark matter.
21cm Signals
Generate toy 21cmFAST lightcones, learn which parameters matter, and compare with upcoming survey sensitivities.
Numerical Experiments
Set up small-box RAMSES runs, visualise the cosmic web, and connect feedback recipes to observable trends.
Structure Formation Study Hub
Track the growth of density perturbations, dark matter halos, and the cosmic web with lecture notes, simulations, and primary references.
