Cosmic Inference: Constraining Parameters With Observations and Highly Limited Number of Simulations

17 May 2019Timur TakhtaganovZarija LukicJuliane MuellerDmitriy Morozov

Cosmological probes pose an inverse problem where the measurement result is obtained through observations, and the objective is to infer values of model parameters which characterize the underlying physical system -- our Universe. Modern cosmological probes increasingly rely on measurements of the small-scale structure, and the only way to accurately model physical behavior on those scales, roughly 65 Mpc/h or smaller, is via expensive numerical simulations...
