Use of Time Dependent Data in Bayesian Global 21cm Foreground and Signal Modelling
Dominic Anstey, Eloy de Lera Acedo, Will Handley
Global 21cm cosmology aims to investigate the cosmic dawn and epoch of reionisation by measuring the sky averaged HI absorption signal, which requires, accurate modelling of, or co…
Marginal Bayesian Statistics Using Masked Autoregressive Flows and Kernel Density Estimators with Examples in Cosmology
Harry Bevins, Will Handley, Pablo Lemos +3
Cosmological experiments often employ Bayesian workflows to derive constraints on cosmological and astrophysical parameters from their data. It has been shown that these constraint…
Finite inflation in curved space
Lukas T. Hergt, Fruzsina J. Agocs, Will J. Handley +2
We investigate the effects of non-zero spatial curvature on cosmic inflation in the light of cosmic microwave background (CMB) anisotropy measurements from the Planck 2018 legacy r…
Bayesian evidence-driven likelihood selection for sky-averaged 21-cm signal extraction
K. H. Scheutwinkel, W. Handley, E. de Lera Acedo
We demonstrate that the Bayesian evidence can be used to find a good approximation of the ground truth likelihood function of a dataset, a goal of the likelihood-free inference (LF…
Bayesian evidence-driven diagnosis of instrumental systematics for sky-averaged 21-cm cosmology experiments
K. H. Scheutwinkel, E. de Lera Acedo, W. Handley
We demonstrate the effectiveness of a Bayesian evidence-based analysis for diagnosing and disentangling the sky-averaged 21-cm signal from instrumental systematic effects. As a cas…
Primordial power spectra from -inflation with curvature
Zakhar Shumaylov, Will Handley
We investigate the primordial power spectra for general kinetic inflation models that support a period of kinetic dominance in the case of curved universes. We present derivations…
