Astrophysical Constraints from the SARAS3 non-detection of the Cosmic Dawn Sky-Averaged 21-cm Signal

H. T. J. Bevins, A. Fialkov, E. de Lera Acedo +4

Observations of the redshifted 21-cm line of atomic hydrogen have resulted in several upper limits on the 21-cm power spectrum and a tentative detection of the sky-averaged signal…

The REACH radiometer for detecting the 21-cm hydrogen signal from redshift 7.5 to 28

E. de Lera Acedo, D. I. L. de Villiers, N. Razavi-Ghods +31

Observations of the 21-cm line from primordial hydrogen promise to be one of the best tools to study the early epochs of the Universe: the Dark Ages, the Cosmic Dawn, and the subse…

Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies

Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200

In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…

GLOBALEMU: A novel and robust approach for emulating the sky-averaged 21-cm signal from the cosmic dawn and epoch of reionisation

H. T. J. Bevins, W. J. Handley, A. Fialkov +2

Emulation of the Global (sky-averaged) 21-cm signal with neural networks has been shown to be an essential tool for physical signal modelling. In this paper we present globalemu, a…

Constraining Quantum Initial Conditions before Inflation

T. Gessey-Jones, W. J. Handley

We theoretically and observationally investigate different choices of initial conditions for the primordial mode function that are imposed during an epoch preceding inflation. By d…

When tension is just a fluctuation: How noisy data affect model comparison

B. Joachimi, F. Köhlinger, W. Handley +1

Summary statistics of the likelihood, such as the Bayesian evidence, offer a principled way of comparing models and assessing tension between, or within, the results of physical ex…
