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…

EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade

R. Alves Batista, M. A. Amin, G. Barenboim +134

Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…

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…

A 21-cm power spectrum at 48 MHz, using the Owens Valley Long Wavelength Array

Hugh Garsden, Lincoln Greenhill, Gianni Bernardi +6

The Large-aperture Experiment to detect the Dark Age (LEDA) was designed to measure the 21-cm signal from neutral hydrogen at Cosmic Dawn, 15-30. Using observations mad…

The subtlety of Ly-a photons: changing the expected range of the 21-cm signal

Itamar Reis, Anastasia Fialkov, Rennan Barkana

We present the evolution of the 21-cm signal from cosmic dawn and the epoch of reionization (EoR) in an upgraded model including three subtle effects of Ly-a radiation: Ly-a heatin…
