In the first part we present a study on\r\nthe contamination of the intrinsic alignments to weak lensing measurements\r\nin the future survey Euclid. On the grounds of the tidal torque theory, we have\r\nadopted from the literature two related prescriptions for modeling the intrinsic\r\nalignment signal and computed for both the resulting biases in the cosmological\r\nparameters.We find a slight discrepancy among the two models, which both\r\nsignificantly (up to > 3sigma) contaminate the estimates for Omega_m and sigma_8. The other\r\nparameters h, ns and w appear less affected. In the second part we present results\r\nbased on an innovative statistical approach, the extreme value statistics.\r\nWe investigate up to which level the primordial non-Gaussianities parameters\r\nfNL and gNL inherited by the bi- and trispectra of the weak lensing convergence\r\ncan be constrained by the most extreme values of the convergence field.We find\r\nconstraints of the order of 102 for fNL and 105 for gNL if individual extreme values\r\nare considered, therefore sadly showing only a relatively weak constraining\r\npower."^^ .
