On the Connection between Field-Level Inference and -point Correlation Functions
Fabian Schmidt
Bayesian field-level inference of galaxy clustering guarantees optimal extraction of all cosmological information, provided that the data are correctly described by the forward mod…

Large-Scale-Structure Observables in General Relativity Validated at Second Order
Antoine Villey, Yonadav Barry Ginat, Vincent Desjacques +2
We present a second-order calculation of relativistic large-scale-structure observables in cosmological perturbation theory, specifically the "cosmic rulers and clock", which are t…

The Renormalization Group for Large-Scale Structure: Origin of Galaxy Stochasticity
Henrique Rubira, Fabian Schmidt
The renormalization group equations for large-scale structure (RG-LSS) describe how the bias and stochastic (noise) parameters -- both of matter and biased tracers such as galaxies…
