An intergalactic medium temperature from a giant radio galaxy
Martijn S. S. L. Oei, Reinout J. van Weeren, Martin J. Hardcastle +5
The warm-hot intergalactic medium (warm-hot IGM, or WHIM) pervades the filaments of the Cosmic Web and harbours half of the Universe's baryons. The WHIM's thermodynamic properties…
Simulation-based inference of Bayesian hierarchical models while checking for model misspecification
Florent Leclercq
This paper presents recent methodological advances to perform simulation-based inference (SBI) of a general class of Bayesian hierarchical models (BHMs), while checking for model m…
Kernel-Based Emulator for the 3D Matter Power Spectrum from CLASS
Arrykrishna Mootoovaloo, Andrew H. Jaffe, Alan F. Heavens +1
The 3D matter power spectrum, is a fundamental quantity in the analysis of cosmological data such as large-scale structure, 21cm observations, and weak lensing. Existing…
On the accuracy and precision of correlation functions and field-level inference in cosmology
Florent Leclercq, Alan Heavens
We present a comparative study of the accuracy and precision of correlation function methods and full-field inference in cosmological data analysis. To do so, we examine a Bayesian…
Parameter Inference for Weak Lensing using Gaussian Processes and MOPED
Arrykrishna Mootoovaloo, Alan F. Heavens, Andrew H. Jaffe +1
In this paper, we propose a Gaussian Process (GP) emulator for the calculation of a) tomographic weak lensing band-power spectra, and b) coefficients of summary data massively comp…
Systematic-free inference of the cosmic matter density field from SDSS3-BOSS data
Guilhem Lavaux, Jens Jasche, Florent Leclercq
We perform an analysis of the three-dimensional cosmic matter density field traced by galaxies of the SDSS-III/BOSS galaxy sample. The systematic-free nature of this analysis is co…
