The expanding universe (cosmology basics)

Cristiano PORCIANI
Argelander-Institut für Astronomie

Chapitres

  1. The cosmological principle
  2. The Friedmann-Robertson-Walker metric
  3. The kinematics of cosmic expansion (cosmological redshift, comoving, luminosity and angular-diameter distances, distance-redshift relations)
  4. The dynamics of cosmic expansion (Friedmann equations, cosmic acceleration and dark energy)

Résumé

We review the mathematical description of the expanding universe in the standard cosmological model.

Bibliographie

Any standard textbook of cosmology will do. Lecture slides include all the relevant topics and specific references.
