SUMMARY:SkyMAD: Building galaxy mock catalogs for large surveys
DESCRIPTION:SkyMAD: Building galaxy mock catalogs for large surveys\nDr. Cl
 audia Scoccola\n\nThe accelerated expansion of the Universe discovered in 
 the late 90's has opened one of the most intriguing questions of modern&nb
 sp; physics. To help to understand its origin, and measure the expansion h
 istory of the Universe, large galaxy spectroscopic surveys are being carri
 ed out and planned for the future. In this talk, I will review the Baryon 
 Oscillation Spectroscopic Survey (BOSS) and the requirements to achieve it
 s precise results. I will then describe a sample of large-volume high-reso
 lution N-body simulations available at MultiDark database,that are useful 
 to test the models. Finally, I will present some work I have been doing ai
 med at producing a large number of mock galaxy catalogs using an improved 
 lagrangian perturbation theory calibrated with these simulations. Mock gal
 axy catalogs are essential to produce reliable cosmological constraints fr
 om these surveys.
