Split personalities in Bayesian Neural Networks: the case for full marginalisation

Kavli Affiliate: Anthony Lasenby | First 5 Authors: David Yallup, Will Handley, Mike Hobson, Anthony Lasenby, Pablo Lemos | Summary: The true posterior distribution of a Bayesian neural network is massively multimodal. Whilst most of these modes are functionally equivalent, we demonstrate that there remains a level of real multimodality that manifests in even the […]

CMB power spectra and cosmological parameters from Planck PR4 with CamSpec

Kavli Affiliate: George Efstathiou | First 5 Authors: Erik Rosenberg, Steven Gratton, George Efstathiou, , | Summary: We present angular power spectra and cosmological parameter constraints derived from the Planck PR4 (NPIPE) maps of the Cosmic Microwave Background. NPIPE, released by the Planck Collaboration in 2020, is a new processing pipeline for producing calibrated frequency […]

Bayesian Data Analysis for Sky-averaged 21-cm Experiments in the Presence of Ionospheric Effects

Kavli Affiliate: George Efstathiou | First 5 Authors: Emma Shen, Dominic Anstey, Eloy de Lera Acedo, Anastasia Fialkov, | Summary: The ionosphere introduces chromatic distortions on low frequency radio waves, and thus poses a hurdle for 21-cm cosmology. In this paper we introduce time-varying chromatic ionospheric effects on simulated antenna temperature data of a global […]

Predicting LyC emission of galaxies using their physical and Ly$α$ emission properties

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Moupiya Maji, Anne Verhamme, Joakim Rosdahl, Thibault Garel, Jeremy Blaizot | Summary: The primary difficulty in understanding the sources and processes that powered cosmic reionization is that it is not possible to directly probe the ionizing Lyman Continuum (LyC) radiation at that epoch as those photons have […]

Being KLEVER at cosmic noon: ionised gas outflows are inconspicuous in low-mass star-forming galaxies but prominent in massive AGN hosts

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Alice Concas, Roberto Maiolino, Mirko Curti, Connor Hayden-Pawson, Michele Cirasuolo | Summary: We investigate the presence of ionised gas outflows in a sample of 141 main-sequence star-forming galaxies at $1.2<z<2.6$ from the KLEVER (KMOS Lensed Emission Lines and VElocity Review) survey. Our sample covers an exceptionally wide […]
