TARDIS. I. A Constrained Reconstruction Approach to Modeling the z ∼ 2.5 Cosmic Web Probed by Lyα Forest Tomography
Benjamin Horowitz,Benjamin Horowitz,Benjamin Horowitz,Khee-Gan Lee,Khee-Gan Lee,Martin White,Martin White,Alex Krolewski,Metin Ata +8 more
TL;DR: Horowitz et al. as discussed by the authors used a fast nonlinear gravitational model to reconstruct the initial density field of the observed regions, which allows accurate reconstruction of smaller-scale structures than standard Wiener-filtering techniques.

TL;DR: In this article, the authors proposed a method to reconstruct the primordial and evolved cosmic density fields from galaxy surveys on the light-cone using a Gibbs-sampling scheme, where the displacement and peculiar velocity fields are obtained from forward modelling at different redshift snapshots given some initial cosmic density field within a Gibbs sampling scheme.
