Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, William J. Handley, Pablo Lemos, Peter H. Sims, Eloy de Lera Acedo | Summary: Bayesian analysis has become an indispensable tool across many different cosmological fields including the study of gravitational waves, the Cosmic Microwave Background and the 21-cm signal from the Cosmic […]

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Harley Katz, Thibault Garel, Joakim Rosdahl, Valentin Mauerhofer, Taysun Kimm | Summary: Limited constraints on the evolution of the Lyman Continuum (LyC) escape fraction represent one of the primary uncertainties in the theoretical determination of the reionization history. Due to the intervening intergalactic medium (IGM), the possibility […]
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 […]

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 […]

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 […]
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 […]
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 […]
