Iterated fractional Tikhonov regularization
Davide Bianchi, Alessandro Buccini, Marco Donatelli +1
Fractional Tikhonov regularization methods have been recently proposed to reduce the oversmoothing property of the Tikhonov regularization in standard form, in order to preserve th…
Semi-Analytic Galaxy Formation in Massive Neutrino Cosmologies
Fabio Fontanot, Francisco Villaescusa-Navarro, Davide Bianchi +1
The constraints on neutrino masses led to the revision of their cosmological role, since the existence of a cosmological neutrino background is a clear prediction of the standard c…
Improving the modelling of redshift-space distortions: I. A bivariate Gaussian description for the galaxy pairwise velocity distributions
Davide Bianchi, Matteo Chiesa, Luigi Guzzo
As a step towards a more accurate modelling of redshift-space distortions in galaxy surveys, we develop a general description of the probability distribution function of galaxy pai…
Optimal order conditions for filter based regularization methods, with applications to variants of the Tikhonov method
Davide Bianchi, Marco Donatelli, Stefano Serra-Capizzano
We study filter based regularization methods for linear ill-posed problems between Hilbert spaces. We derive optimal order conditions under a-priori choice rules for the regulariza…
