FuGa3D: Fast full-sky analysis of Galaxy catalogs in 3D
Elina Keihänen, Jani Haapala, Valtteri Lindholm +4
We present FuGa3D, a code for fast computation of correlation functions and power spectra for galaxy survey observables, including galaxy clustering and cosmic shear. We define the…

Fast, Accurate and Perturbative Forward Modeling of Galaxy Clustering Part II: Redshift Space
Julia Stadler, Fabian Schmidt, Martin Reinecke +1
Forward modeling the galaxy density within the Effective Field Theory of Large Scale Structure (EFT of LSS) enables field-level analyses that are robust to theoretical uncertaintie…

Fast, Accurate and Perturbative Forward Modeling of Galaxy Clustering Part I: Galaxies in the Restframe
Julia Stadler, Fabian Schmidt, Martin Reinecke
Forward models of the galaxy density field enable simulation based inference as well as field level inference of galaxy clustering. However, these analysis techniques require forwa…
