El prof. Crocce pronunció la siguiente conferencia en el workshop The Nature of Dark Energy:

Dark Energy with galaxy surveys

"In this talk I will present a comprehensive model for this clustering signal at large angular scales as a function of redshift and bin width, including all relevant effects, namely nonlinear gravitational clustering, bias, redshift space distortions and photo-z uncertainties. We also discuss, and test against simulations, a model for the full covariance matrix characterizing the angular correlation measurements. One interesting outcome is the potential of photometric surveys to yield constrains in the growth of structure through redshift space distortions".
