Alignment of the Milky Way and M31 with their cosmic environment. New insights from constrained Local Group simulations
Hanneke C. Woudenberg, Amina Helmi, Ewoud Wempe +4
Using constrained simulations that reproduce the observed Milky Way–Andromeda configuration, the authors examine how the surrounding Local Sheet influences the shapes, spins, and d…
Application of Bayesian Statistical Tools to SKA Telescopes Polarization Surveys to Study Magnetization of the Large-scale Structure of the Universe
Valentina Vacca, Sebastian Hutschenreuter, Andrea Cabriolu +18
Understanding cosmological magnetic fields requires a detailed knowledge of magnetism in the different environments of the large-scale structure of the Universe. Magnetic fields ar…
Two per cent measurement of from Cepheids alone
Richard Stiskalek, Harry Desmond, Eleni Tsaprazi +4
One of the most pressing problems in current cosmology is the cause of the Hubble tension. We revisit a two-rung distance ladder, composed only of Cepheid periods and magnitudes, a…
Learning the Universe: Constrained simulations of the Coma galaxy cluster -- I. Radial X-ray and Compton-y signatures
Ulrich P. Steinwandel, Stuart McAlpine, Richard Stiskalek +7
We present a suite of 50 high-fidelity simulations of Coma cluster analogues constructed from BORG/MANTICORE constrained initial conditions and evolved with the IllustrisTNG galaxy…
Learning the Universe: Posterior Reliability of Neural Generative Models in High-Dimensional Field-Level Inference of Cosmic Initial Conditions
Ludvig Doeser, Jens Jasche
Accurate posterior estimation is central to scientific inference, as uncertainties determine what can be reliably learned from observational data. While Markov chain Monte Carlo me…
The Manticore Project II: Bayesian digital twins of cosmic structure across the SDSS and BOSS volumes
Stuart McAlpine, Jens Jasche, Guilhem Lavaux +2
We present Manticore-Deep, a high-resolution Bayesian field-level reconstruction of cosmic large-scale structure over a comoving volume of to $z\approx…
