A differentiable forward model for weakly perturbed stellar streams: substructure forecasts from density and kinematics spectra
Noemi Anau Montel, Fabian Schmidt
Stellar streams are a promising way to gravitationally detect low-mass substructure, since their low dynamical temperature makes them retain the imprint of weak gravitational pertu…
Cosmological hydrodynamical simulations of clustering dark energy with Nefertiti
Linda Blot, Théo Gayoux, Fabian Schmidt +2
We present the first cosmological simulations that consistently include nonlinear clustering dark energy evolved as a fluid with the numerical hydrodynamics code Nefertiti. Dark en…
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…
