Constrained cosmological simulations of the Local Group using Bayesian hierarchical field-level inference
Ewoud Wempe, Guilhem Lavaux, Simon D. M. White +3
We present a novel approach based on Bayesian field-level inference capable of resolving individual galaxies within the Local Group (LG), enabling detailed studies of its structure…
Bayesian Inference of Initial Conditions from Non-Linear Cosmic Structures using Field-Level Emulators
Ludvig Doeser, Drew Jamieson, Stephen Stopyra +3
Analysing next-generation cosmological data requires balancing accurate modeling of non-linear gravitational structure formation and computational demands. We propose a solution by…
An Anti-halo Void Catalogue of the Local Super-Volume
Stephen Stopyra, Hiranya V. Peiris, Andrew Pontzen +2
We construct an anti-halo void catalogue of voids with radii in the Local Super-Volume ( from the Milky Way), using…
Towards Accurate Field-Level Inference of Massive Cosmic Structures
Stephen Stopyra, Hiranya V. Peiris, Andrew Pontzen +2
We investigate the accuracy requirements for field-level inference of cluster and void masses using data from galaxy surveys. We introduce a two-step framework that takes advantage…
Constraining modified gravity with quantum optomechanics
Sofia Qvarfort, Dennis Rätzel, Stephen Stopyra
We derive the best possible bounds that can be placed on Yukawa- and chameleon-like modifications to the Newtonian gravitational potential with a cavity optomechanical quantum sens…
Quantifying the Rarity of the Local Super-Volume
Stephen Stopyra, Hiranya V. Peiris, Andrew Pontzen +2
We investigate the extent to which the number of clusters of mass exceeding within the local super-volume () is compatible wi…
