Sommer Semester 2014The course will cover advanced topics in Cosmology:Theory:  Beyond the standard cosmological model  Inflation  models and phenomenology of dark energy  models of modified gravity: extradimensional gravity, higher order gravity, massive gravity, screening mechanisms  non linear clustering (PressSchecter, higherorder perturbation theory)  Inhomogeneous models Observations:  supernovae  redshift clustering  lensing  cosmic microwave background  Bayesian statistics  The ESA Euclid satellite NOTE: Course begins on April 28th, 2014 classes on Monday 14:1516:00 Philosophenweg 12, R106 Calendar (to be confirmed): 28.04 05.05 No lecture today 12.05 19.05 26.05 02.06 seminar by Dr. Miguel Zumalacarregui. Compact Notes and Extended Notes . Abstract: Recent observations allow us to test the validity of Einstein gravity on both cosmological and Solar System scales. I will give an overview of alternative theories of gravity, emphasizing the additional degrees of freedom that they introduce and focusing on scalar tensor theories, both of the JordanBransDicke and the more general Horndeski class. Then I will present the different effects by which modified theories of gravity may have sizeable cosmological implications while remaining indetectable in the Solar System, focusing on the Chameleon mechanism and the Vainshtein effect. 09.06 16.06 seminar by Dr. Alicia Belloso. Notes. Abstract: The Fisher Matrix in cosmology: I will introduce the concept of the Fisher matrix and how it is a useful tool to calculate forecasts for future cosmological surveys. I will also calculate explicitly the Fisher matrix for the matter power spectrum and indicate the results for the CMB, supernovae and weak lensing. 23.06 30.06 07.07 14.07 21.07 (SR 105.)
