Halo detection via large-scale Bayesian inference

Merson, Alexander I.; Jasche, Jens; Abdalla, Filipe B; Lahav, O; Wandelt, Benjamin; Jones, D. Heath; Colless, Matthew


We present a proof-of-concept of a novel and fully Bayesian methodology designed to detect haloes of different masses in cosmological observations subject to noise and systematic uncertainties. Our methodology combines the previously published Bayesian large-scale structure inference algorithm, HAmiltonian Density Estimation and Sampling algorithm (HADES), and a Bayesian chain rule (the Blackwell–Rao estimator), which we use to connect the inferred density field to the properties of dark...[Show more]
