Cosmological Parameter Estimation with Large Scale Structure Observations

20. November 2013
Cosmology Seminar, ITP Heidelberg
I will present a recent Fisher matrix forecast on cosmological parameters based on 2D angular power spectrum for Euclid-like surveys. I will show that the analysis with redshift dependent angular power spectra leads to comparable results as the usual analysis based on the 3D matter power spectrum. Contrarily to the 3D analysis, the 2D-tomography analysis is model independent and directly observable. All the results have been obtained using CLASSgal, a code made now publicly available, which computes, accurately and efficiently, the galaxy number fluctuations in linear perturbation theory, including all relativistic corrections.
